Otterbox is doing their usual Commuter/Defender. The Defender in the picture looks like just a hard case though, no silicone outer jacket. Weird...
Ballistic Case is releasing a SG case and the SG Maxx for those that want a belt holster. The SG has always been my favorite case. I've never used the MAXX but it looks promising.
Nothing over at Trident Case yet.
Seidio looks like they're getting things ready but nothing official yet. Let's hope they make an extended battery and matching case.
