Hardcore!!!! OMG its amazing only just tried it and its awesome i love how you start with about 60% health and it doesnt regenerate unless you find a medics health crate, also feels a lot more real and it forces more teamwork. They also kept the mini map in hardcore which they didnt in BC2.
VOIP!! Did anyone else know about this? I always wondered if there was an option to talk to the whole team and then just yesterday when i paused i noticed it said VOIP I changed it to team and then all of a sudden i was talking to teammates :)
Also noticed the lack of realism servers, I did find a good one yesterday called Royal Marines Simulation server which was awesome, wish you could customise the hardcore settings slightly to make it more challenging without it becoming unranked, although this server had was ranked with custom settings so it means you started with 100% instead of 60%.
