Interesting enough the M14 and the SCAR-H are now assault rifles for the assault kit. The M39 is a DMR.
The AK971 is back of course, but the AK74 appears to have been replaced with the AK12
Furthermore it looks like they are trying to bring in more 7.62 battle rifles into the game. If the FAL is available ill be as giddy as a highschool tween out at a twilight premier.
Engineers now are the only ones that have PDW's no more LOL god mod engi's per say, though Carbines are now all kit weapons, so I'm not sure what to make of that.
They have brought in one of my all time favorite rifles as an all kit weapon the Swedish AK5c (one super sexy gun if you ask me) among other things. It's still a little early to say, but the game is looking really good.
Fully customizable handguns will be nice, laser pointers, sound suppressors, ghost wring irons (will make the Rex much easier to aim) so far it looks like a lot of the issues people complained over in BF3 is being addressed.
Another intriguing thing I saw was the "High Value Target" resource the commander has. So I wonder, is this kind of like the bounty system from home front where a "bounty" can be placed on a player that is doing very well and is being a pain to the other team? Designating a specific player as an objective possible? If that is the case, I welch it with mixed feelings. While useful 8 can see it being abused and used to troll people.
