As far as I know, the next phones that we can expect in Big Red's lineup that are worth noting are the aforementioned RAZR HD and the LG Optimus Vu. Now the RAZR HD is likely to be similar to be quite similar to the Atrix HD, with perhaps a higher megapixel camera. Thing is, it should have come out a month and a half ago and is likely to be akin to the Bionic with the "nice option but too late to the game" tag.
The Optimus Vu I suppose is supposed to be the answer to the Note that we were supposed to get, but who'se ferver has quelled significantly. Thing is with the Note 2 already in the pipeline for AT&T, does anyone really care?
Considering we just got the Incredible 4G, I don't see another HTC coming anytime soon unless it's closer to the One X, but with some newer features.
Let's face it, the Galaxy S3 is not just the best option right now, but I think will continue to be for the foreseeable future. Reason this is my opinion is because it's actually bringing innovation that other manufacturers haven't considered and the phones that are confirmed in the pipeline have had zero mention of anything comparative.
