I feel neutral on the matter.
On the one hand, I'm all for change and progress and innovation and trying new things. I'm firmly in the camp of, "I'll try anything once, twice if I like it."
But on the other hand, I'm a pessimist and skeptic by nature and everything about this is just screaming at me, "Failure, failure, warning D&D player, warning!"
The thing that puzzles me beyond measure is why they felt the need to announce it NOW. It's not like this will boost 4e sales. There just seems like every reason NOT to announce it now and no reason to announce it, at all.
Yet here we are, in the post-4e era; and let's not kid ourselves, 4e is now dead. Announcing a new edition is the nail of all nails. I certainly won't be looking at any new 4e content and have no reason to renew my DDI sub.
What REALLY worries and puzzles me is that they don't seem to have learned any lessons from their predecessors... or themselves. They're promising everyone, everything, and yet have nothing concrete to offer anyone, anything. So now here we are, post-4e era, in EXACTLY the same position we were in pre-4e when 4e was announced and GleeMax was a buzzword and the Virtual Table Top was going to revolutionise the game and 4e was teh awwsomnest!!? editionz EVAR!
Yeah. And it's snowing in Hell right now, right?
