Galaxy S III is coming to all US carriers (real US carriers) in a few weeks...including Verizon. I believe it may actually be the same exact phone on each carrier (they say it's LTE and HSPA capable), which would make the Verizon version by far the best (assuming you have Verizon), since you could use their 4G LTE network, or unlock the phone and use AT&T or T-Mobile's HSPA networks. Anyway, it's based on (or is) the Japanese version, which has the 1.5Ghz Snapdragon 4 (Krait) CPU and 2GB RAM, which basically smokes everything else. I believe I will be purchasing one ASAP, the best thing ever would be if Samsung releases a lapdock-like add-on like Motorola has for the Atrix, Bionic, RAZR, etc.
Edit - I may have spoken too soon about them all being the same phone (as in LTE and HSPA), but the best part is that since it's launching on all of the networks, Verizon can't jack up the price like they typically do (16GB is $199, 32GB is $249). I hope VZW continues their trend of including 32GB microSD cards, though 64GB would be really nice. I don't know what I would need ~96GB of storage for, but 1080P videos take up a lot of space.
