a lot of it looks new and cool but i saw way too many assets being reused in that gameplay. knifing, russian character models, the buggy, etc etc
im assuming bf4 is supposed to be set literally just a few months after bf3, also don't expect to just be fighting russia again, they're clearly bringing in china.
as for what BF4 will be running on, it will be running on PS3, and Xbox 360, and the next-gen consoles.
@fred, they're adding lots of more of physics improvements, if you noticed in the 17 minutes of gameplay, they distinguished building being clobbered by a grenade launcher, and i'm assuming you'll be able to dive underwater in this game now, with a full underwater floor model. i'm assuming they're also increasing the draw distance, and increasing the quality of their textures. normal maps like caspian border and op. firestorm are now going to be different maps only 1.5x the size they were in BF3
I wish that dice would just cut the campaign and focus all their resources on multiplayer and bug testing so the alpha isn't unplayable like last time.
they add campaigns to appeal to the gamers interest other than just multiplayer, and also it provides a first-person perspective on to why you're fighting in those multiplayer maps.
