Ok, noted.
If they give me the options I want out of it, then yes I'll play it. I may buy it used so that WotC doesn't get any of my money, but I will definitely play it.
I will admit that what we have seen so far is far enough away from a game that I want to play that if the finished product looks 85% like it, that I won't play it. However we can still change that with feedback.
It doesn't matter if there is almost no chance of me getting any changes in at this stage of the game. I'm going to keep trying right up until this thing goes to the printers. Then I'm going to wash my hands of it. And explain to the people that ask me "Why didn't you give feedback and ask for changes to be made and speak up." that I did right up until it released. So there will be no excuses when many 4E players don't migrate and instead choose something else like 13th age or just stick with 4E.
IIRC, didn't you say a couple of weeks ago that you buy all of your WOTC books used so they don't receive any money from you? If so, then you've really sacrificed any right to expect WOTC to listen to you. If you go out of your way to make sure WOTC doesn't make any revenue from you, why should WOTC listen to you?
