So, Mr. Butt...given your sig, you seem to be a fictionsuit created specifically to protest 3.5e. Sort of like Sauron-With-Pokey-Helmet before Fellowship of the Ring came out. What happens in August when you're out of a job? What if the revision is actually good?
How about this: YOU wait for 4e if you like. I might just do the same thing, if 3.5 isn't what I want. But I'll wait and see.
That said...WotC is indeed working hard to make the revision compatible. But no matter what they do, they can't make truth out of a lie: "v.3.5 will not make key game accessory and supplement titles obsolete." Um, how about the Core Rules?
The issue I have with this Revision is not with it being too soon (in some cosmic RPG schedule), but rather the fact that it was rushed. It's all been smoothed over, but there's been talk of them not having enough time to playtest certain things...and the fact that they fired all their "name" designers about halfway through development...
I fear the worst, but I hope for the best.
Mr. Butt...you are now "unofficial." But take heart...you're still "backwards compatible."
