Waheey at least I'm not the only one. Though I was 4 hours faster than Dice as I've just got the email too :p
First impressions looks good. Yes it crashes a lot (but its an early build). New lighting looks impressive and little things like looking into a dark room from outside in the sun look realistic in the fact you can hardly see in.
Hit reg is a million times better than Bad Company :) Nearly as good as COD 4 (on a good server) and the fact my aim is off with the iron sights and recoil doesn't help.
Only downside is that soldiers still throw grenades like girls i.e only about 15m away
