Yeah I was discussing this last night as I met a couple of sound yank lads and an English fella in one game so we stuck together most of the night.
It looks tbh like they have too much to "patch" before release so they're probably just going to rush It out before MW and get as many sales in as they can then bring out the patch as soon as they can.
BC2 beta was a glitchy mess too but I put serious hours into that, was about 500th in the world at one point, but it turned out to be the best game I've ever played.
The lads I played with also had the beta loading on their PC's and said it does look so much better, which we all knew would happen.
I know what betas are like so atm I'm happy and looking forward to the full games.
Jets ffsnake!!!
They also said the developers have been playing caspian boarder too so they'll be testing all aspects.
