What are you expecting for BF4?

Im realizing alot of people are talking about BF4, I know it seems a little soon, but I think it would be interesting to see what people are expecting. Such as weapons you want to appear, and guns you want to return. Customization options might be worth mentioning, but I would like to focus on the gear. I hope for a wider selection of weapons, different equipment or at least more, and better secondaries. I play as Recon alot and none of the handguns suits me, also I'm wondering what people think about bringing back one shot kill snipers. Was it really that annoying in previous battlefield games?
