There are double the characters on the online version than there are in the base game. I like some of those characters better than the base game characters and would love to "own" them. Is there going to be a tabletop version of Puzzle Strike that includes them? Does the Print and Play version already include them?
Those 10 characters are planned for the first full-sizes expansion and still in a stage of development (a very sophisticated stage though). So - no, those character have not yet been published in a physical edition.
Also, the 'base set' character chips and puzzle chips presently used in the online version are not the same as those in any existing published set.
The characters (by name/image) are the same, but the character chips have gone through two generations of changes to reach the state they are online right now. The first generation of changes is represented in the upgrade pack; the second generation of changes is as yet not published nor announced for publishing. The puzzle chips (and Combine chips) were issued changes at the same time as the second-gen character changes, and likewise have not been published nor announced for publishing.
