The Hans im Gluck page has a German PDF up with the rules!!!
I don't read German...at all - so here is the translated text (courtesy of a babblefish & google) for the new expansion (with some correction by me - my comments are in italics):
In good company - The Banquet by Tom Lehmann, Karl-Heinz Schmiel
and Michael Tummelhofer
"In good company" consists of 36 cards (for better distinction with a
purple dot), 2 black wooden figures for the 5th player, and a
Gold disc for a five player game. Additionally to the new parts, which are necessary for the five player game, This contains of "The New Society" - some cards which are added to the existing game, or replace existing cards of the game.
"The Banquet" consists of 12 cards (for better distinction with a yellow dot marked). The new cards consist of 1 new craftsmen, 2 new buildings and 9 special cards with features that are very different from the normal craftsmen, buildings and nobles.
Both expansions can be used individually or together, but only in conjunction with the Basic game. It can also by played with only individual cards. We However recommend in the first game use the complete set of expansion cards.
This expansion can be used only with St. Petersburg base game. Except for the following exceptions apply the normal rules of the basic game.
In Good Company
Preparation: Before the start 7 cards are removed from the basic game: 1x tsar and Carpenter (craftsman), 2x observatory (building), 1x academy (building), 2x Hofmeisterin (noble), 1x Marinskij theatre (exchange card) These cards are replaced by cards from this expansion. Do not use both versions of the cards in a game. The expansion cards are placed according to their backs into the appropriate piles.
Only in a game with 5 players are the extra player card and the gold disc is required. A player mixes the 5 starting player cards and distributed it to the players.
The player with the gold disk keeps 2 roubles additional at the start of the game (totalling 27 roubles). The player with the gold disk does not start any round. The player instead receives at the beginning of the craftsman round 2 points. Only the player, that has the gold disk at the beginning of the game, gets the additional 2 roubles.
The game with 5 players runs, with the following Exceptions, as normal: In the first craftsman round 10 craftsmen are placed in play. In all following rounds (also that the following craftsman rounds) only 8 cards are placed.
After the exchange round the starting player stones are passed 2 players to the left, instead of at the direct Neighbour.
The end of the game and scoring
If one or more players at the end of the game have more than 10 different nobles played, these players receive for each nobles after the tenth, 10 points.
The new cards:
Tsar and Carpenter are cheaper (3) but players receive however only 2 roubles (until a replacement card is placed). green card with 3 cost, pays 2 gold
Coffeehouse gets 1 ruble for every noble played by the player.blue card with 6 cost
Debt Tower scores one point a turn, unless used as follows:
He may once in the building round the browse the Stack/Delivery Pile (I _think_ this means discard pile) and choose a card. This card must be bought and used immediately, placed in the hand or put back in the Stack/Delivery Pile. In every case the card is flipped over and receives no points this round. A turned over card can not be replaced. At the beginning of the next round he turns it back over and it is again available. blue card with 8 cost
Trade House: Immediately after each scoring of buildings, the player can buy 2 points for 3 roubles. This ability may, in contrast to the inn, be used only once per Round. blue card with 2 cost, and a 2 pt=3 gold icon
Academy: costs more and gives 9 points in the building round. blue card with 25 cost, 9 point payout symbol

It looks great! I can't wait to try it! Thanks for the post
Die, human scum!
Resistance is useless!
Lt. Kije cracks me up.
Image is from Turandot. It looks just like me.
The player with the gold disk does not start any round. The player instead receives at the beginning of the craftsman round 2 points.
This seems like a strange rule that will essentially affect everyone virtually the same. 2 Rubles seems like a more fair reward as the player gains a benefit that round to afford some cards that others might be able to. But I'll trust Tom Lehman (for now).
Not going first in any phase of the very first round is a disadvantage, which is why the gold disk player starts with 2 extra rubles. After that, it's not as important (remember that roles get passed two spots left in the five player game), so things are essentially a wash, with players that get the gold disk twice (in a 6 or 7 turn game) receiving 2 VPs more (net) than the other players.
