Tough to say for sure, but this seems like the "note" like device for HTC since it's got a 1080p display. That would be a bit overkill if it's not 5" plus. Resolution suggests onscreen buttons which would be an HTC first. Gonna be some pretty interesting late summer early fall VZW stuffs it seems.
The Dev SGSIII I think could be as successful as the current Nexus with many looking to preserve their unlimited though. Not to mention Samsung should be free to release proprietary binaries for it LONG before they could get the full on VZW approved TouchWiz stuffs out. That thing could prove to be almost as nice as having a Nexus in these regards if Samsung handles it right. We'll see.
Such things seemingly haven't happened with the Rezound which in unlockable, so it's tough to say. Samsung does up and send devices to devs for free though, so you never know.
I personally want a 5" HD physical Qwerty device. I would drop the GNex in a heartbeat for such a device even if the thing was locked up with limited dev support. I'm so doubtful that will happen though that I am preparing to keep the GNex for a long time. Atleast until there are several A15 devices out. A Nokia PureView device running Windows Phone 8 could be interesting also. The lack of camera innovation is kinda a bummer. They are all good now, but would be cool if something more extreme in sensor size existed on an Android device. I am a huge minority in my acceptance of a massively thick device to enable such things though.
This is a phone to be released before the next IPhone?
Hard to say with VZW. Apple seems to have devices ready and approved with all the launch networks LONG before any official word or timeframe for the device gets a firm leak. This device will probably more or less show up when HTC finally convinces VZW it should be released. Apple has more control of such thing than HTC will have essentially. Still clueless how Samsung pulled off what they did with the SIII, but it was still not as smooth and controlled down to the day as the iPhone4S that launched on a similar line-up of networks all at once.
Possible first leaked pictures? Looks pretty nice if you don't HAVE to have Phablet and something almost SIII sized will work. Display looks a good bit closer to the edge than even SIII maybe. Seems we have a bezel minimization trend now.
DL is speculating this isn't it, but never know what might have came of onscreen buttons from some early test builds and hardware. Posting this here cause it looks too thin compared to size to be a smallish device(unless it's like 7mm which is unlikely).
