I'm all for a little back-to-basics.
Really, I like the idea of a new, generic, by-the-numbers, but high quality setting.
With things like templates (which I imagine will still be around in one form or another), and all the changes, the generic of yesteryear is no longer truly valid.
French Vanilla is out. This is the age of Vanilla Bean. It's still vanilla, but it's not the same Vanilla no matter how much the word Vanilla throws you off.
A new setting with level 30 warlock queens and fighters who can backflip over giants and stab them in the ear or whatever needs to be made, because darnnit, rewriting old settings and using those as core examples gets silly, -fast-.
