sorry, dude. generally speaking, he was right on the money.
whether Gabe is upset or not and whether the 360 has all the extra features and access or not, 360 gamers will buy the game more than PS3 gamers. it's bound to happen. 5:1 is unlikely, but the 360 version will most likely have a decided sales advantage, whether there are awesome custom maps and extras or not. past FPS sales data lends credibility to the educated guess/conjecture. as such, Valve will support the 360 version just as well as the PS3 version. it's about who's buttering your bread...and quite frankly, chances are great that the 360 gamers will be spreading more butter around. Generally, they always do.
so in the end, all this is much ado about nothing. MS won't change the policy because it's working well for them. They have a walled garden that they're comfortable with, much like Apple does with their App Store. the day it stops working as a net positive for consumers and developers is the day the system changes. Not because Valve wants special privileges because they're a great developer who can be trusted.
count on all of that. and in your future posts, you can try to be less condescending towards your fellow posters. your point wasn't so blessed that it was deserving of your ridicule and brow-beating. you were neither correct nor intellectually honest in your critique. perhaps you should try less to get cool points from some posters by insulting others..and in doing so, become respected by all.
just some thoughts.
