probably won't play 4e, but will stick around anyway and whine until every last 4on sees the errors of his ways.
More seriously, I will probably give it a try as is but can't see myself buying the books. There are already so many things that rub me the wrong way that I feel like a krenshar.
The dealbreakers are so tied to the design philosophy and the core of the game that they would be impossible to ignore and houseruling them would be too much effort.
Which is a shame because I was really looking forward to a new edition, well before it was announced, and there are many things i do like about 4e.
