Your, "WotC is just trying to keep the lights on" argument continues to not impress me. I know for a fact that there are plenty of people here at least who would have loved to see WotC make a legit new edition that actually fixed core issues. This isn't about me, even though I of course have a personal opinion.
Who's to say if a new design that tackled the problems of the previous one wouldn't have been enough to "keep the lights on" (I really hate that phrase in association with a huge corporation)? There's no way to know.
