If this is the first we're hearing/seeing of it, we probably don't have to worry about it coming out til sometime this summer anyway (I'll say June as my guess, to try and jump-start the '3rd quarter lag'). But, I bet the phone will just be the Razr Maxx with a larger screen (Razr SupaMaxx maybe? I should TM the name before Moto steals it). I'd assume we would see the Razr/Maxx with an HD screen first, and that could sneak in at any point (as it already exists overseas, and wouldn't be difficult to keep quiet as the Maxx was).
And in this day and age of cell phones, where the newest and greatest is just months away, older models 'going to waste' is unavoidable, but 'waste' is relative. I had a DInc and love the phone, even still. It was a very good/solid phone and performed quite well.
