User blog comment:Bovell/Kotaku claims to have MW3's first look. Robert Bowling responds. (Minor spoilers)/@comment-3350627-20110513164958

From the looks of the photos, here's a list of confirmed weapons. Skorpion (with black furniture) MP5A4 (full size MP5, with front rails) SCAR-L (in black) MP412 (Russian .357 revolver) M14 EBR Remington RSASS (A JP Rifles based sniper rifle) Model 1887 (With black furniture, and M1014 style sights) Remington ACR (in tan) P99 (Duotone) AK47 (Looks like MW2's with black furniture) M82 Barrett .50 Cal (Seems to be a MW staple) Armsel Striker (The infamous MW2 shotgun) M320 (Portable grenade launcher, Thumper replacement?) AA12 (has some rails n' junk thrown on it) Kel-Tec KSG (Or something. Bullpup pump action shotgun.) The one and only M4A1 (EOTech and magnifier, as well as a Magpul CTR Stock) G36c (Hooray!) Magpul FPG (Probably a G18 replacement) BTW, I found these on a different article on Kotaku titled "MW3 Multiplayer features battles in Brooklyn, clash in Mogadishu."
