Just because it's requested doesn't mean it's coming.
Custom browser server has it's own host of issues aside from just "splitting" the player base.
We haven't seen dedicated servers for Halo before, no reason to suspect them now and if they WERE coming I'm sure it would have been one of the first things announced (that's a pretty large selling point).
Yeah...Halo 1 PC, which btw had the best online structure of any Halo game. They will not split the userbase, they will unite them.
I also doubt anything near the biggest Halo 4 features have been announced yet, if they have...lol
I genuinely expect dedicated servers at least, if Gears 3 had them, why on earth wouldn't Halo 4? Either way, I can't believe I'm seeing people trying to defend a forseen lack of these features, it's absolutely disgraceful if they don't make it in. We shouldn't be paying for an inferior service, it's an absolute con.
