Hopefully things like the Twilight Knight upgrade from the white box makes it into 1.5 as core since a bunch of us would have already applied the sticker to our existing rulebook. I suspect they will but will have to wait and see. Either way, new hardback rulebook for the upgrade pack is cool.
I also had my rule book spine cut and spiral bound and it was ruined. Company said pages slipped when they punched for spiral binding so they double punched those pages and all were not aligned correctly. One thing I was really hoping for with this KS was to obtain a new book. I'm so happy it's coming with the upgrade kit! And a hard cover version is even better.
I ended up getting a full refund and then used that to buy page sleeves which I then bound in a black cover piece, so my old book survived in some sense. It takes up more table space now, but it will open completely which was the intent with spiral binding originally.
