I was looking for an upgrade too, but when i heard sgs3 would be coming to verizon i am holding off for this one.
i would not jump on the razr maxx either, as i was going to pull the trigger and found a rumor that the razr maxx HD version (720p) will be released before or around the same time as the sgs3. also notice how the razr maxx dropped to $200 is a big red flag that a new phone is coming soon.
the rumor on the exclusive deal for verizon has made its rounds, as it was stated verizon may have a deal with samsung to release the phone before any other provider (ATT, T-Mobile, or Sprint). As this phone is the sponsored phone for Olympics i would doubt the "exclusive" release would last merely a week or two.
though samsung did guarantee the phone will be available in 120+ countries by july does mean june is the date on or around the 20th
remember all rumors are not confirmed
