Okay, having watched the videos, and being the kind of person who is always willing to try out a new system, my general feeling is ... wow, way too many flashy fiddly bits.
I have enjoyed playing WFRP a few times in the past, under the first edition; I definitely liked the career-character creation, even though it gets rather silly at points. I have read some of the current edition books. Warhammer is generally a little too dark for my taste, but that is easy enough to fudge a bit from campaign to campaign, and I like the Renaissance (rather than Medieval) feel of the setting. So much for my WFRP background.
Now this game has me worried not in terms of the fluff, but the crunch.
Okay, it looks pretty. Pretty books, pretty sheets, pretty components ... and components ... and components. You have to get very particular dice, not just generic dice, and of many different kinds. You need cardboard bits ... of many kinds ... and cards ... and particular sheets ... and the group sheet... This means you need a lot of space at the table and that you need to keep up with such materials for each and every supplement. And if a particular future supplement becomes very popular, that means a lot of these fiddly bits will have to be bought in multiple copies (which will, one hopes, be available separate from the books themselves). This game sounds like a very expensive proposition.
However, I will admit that the concept of the "group sheet" in and of itself is intriguing to me; it reminds me very much of the covenant in Ars Magica, the "overcharacter" that everyone contributes to and links everyone together. This is, in many ways, the most intriguing part of the game as it was presented in the videos. I am not sure I am excited about how the sheet seems to work (especially the "set crisis points"), but broadly I like the notion.
Anyway, initial impressions based only on the videos; the release of the game itself may change all of this.
