They could be attempting to get ahead of the shift of business users from blackberry to android and IOS phones. The Blackberry has been Sprints business phone, and unless they end up getting the Iphone, they need a business Android phone to handle that shift. It doesn't feel very businesslike to be using a 3D entertainment device!
I think Sprint is really missing out on hammering that they are the only ones left offering unlimited data. I would be running Ads showing ATT and Verizon users scared to watch a youtube video because they were going to run up against their limits. But business users also will want to be able to tether this phone or at least use it with a bluetooth keyboard and dock when on the road...would be really nice not to have a separate data plan for a laptop and a phone. With these great phones and unlimited data Sprint really should be #1 and not number 3.
