Woodysgamertag released a video explaining the perks and he told us he got them from a reliable source; however his video got removed by Activision for copyright, so it must be true, right? I'll let you decide. Anyways, here are those perks:
Extreme Conditioning - Sprint longer; Pro - Climb Faster Sleight of Hand - Faster Reload; Pro - Swap weapons faster Scavenger - Resupply ammo; Pro - Start with extra mags Blind Eye - Undetected by air support; Pro - Quicker lock-on + Extra damage to air support Recon - Marks enemies damaged by explosives; Pro - Marks enemies damaged by bullets

Again, since Activision got the video removed from YouTube i am pretty sure it is true. He says that he knows all the killstreaks too and he actually made a video about it. But Machinima told him that he shouldn't upload that video.
Yeah... Just like Black Ops turned like MW2. Before the BO release you thought that there would be so much new great stuff but there isn't. It ended up just like MW2, except that you buy stuff instead of unlocking. And MW3 will indeed end up just like Black Ops.
