Hmm...I still have my MoH: Warfighter disk, which supposedly guarantees entry...
I won't be playing it on 360 anyway though (which I presume is the beta access I'd get, as it's the platform I have MoH on), so I'm not too bothered either way. Had a bit of a nightmare with the BF3 beta as it was anyway, to be honest.
EDIT: You guys are talking about alphas, not betas.
I remember there was jamming in beta or was it alpha.... there was lots of little things. I know a bunch of people who got into alpha...but you can only play at specfic times I guess
