That was a long time ago. WOTC is different now, with top notch programmers. Look how well they did with Sigil!
Sigil was a half-formed idea looking for a reason to exist. Any game is vaporware until released of course, I just don't think past performance has much bearing in software development. Some companies that once produced amazing games produce crap, other companies I've never heard of come up with some pretty good stuff.
