Well, it's certainly made 'general RPG discussion'
extremely 4e-centric. Is that how 'General' is meant to be?
Also, 4e will still get, essentially, plenty of free publicity in 'General'. Which is fine, of course! But Pathfinder, on the other hand? People will have to know about it already, else all they might hear about (here) is 4e - that is, if you don't know about it yet, why check a forum dedicated to that thing you've never heard of - and the occasional bit of OD&D/BD&D/AD&D, and maybe a random mix of other games at times.
Not to mention, products and services that come out for either system. That's where it will be
exceedingly unbalanced and unfair, constantly. Say, new things are made for DDI, or D&D minis, or
4e supplements are discussed, like. . . MM2? MM3? Demonicon? Anyway, whatever.
Those things will get plenty of threads in 'General',
as is the case right now. Compare: suplpements, minis, software, services, whatever else is / will be for/about
Pathfinder - it'll have to be in a less frequented (than 'General'), specialised forum that is most likely to be visited at all by those already decided on / invested in that game, obviously. Well, that, or it'll get shunted there ASAP.
And this right now, with Pathfinder just released!

Terrible timing, even if such a curious move 'had' to be made for some bizarre, as yet unspecified reason.
I know that was kinda verging of a

. But I feel it needed to be said. And heard.
Anyway, I hope that all makes it a little more clear, exactly how and why things are already
heavily skewed in favour of 4e (and, by extension, WotC) - and how that isn't going to get any better with things as they stand.
Please do reconsider.
