The NEX 5R is coming on August 28th according to Sony Alpha Rumors - and Sony is finally taking DSLRs into the ’10s. This camera features a new app platform (a first on a camera like this).
The camera has WiFi built in and the apps could be more interesting than just a few gimmicky filters, because it is possible Sony may provide a full SDK / dev kit for developers. This would be required if third party apps are planned. But it may also be the case that only Sony will provide apps, with each firmware update.
A dev kit is basically an open door for hackers to improve video functionality, after which we won’t call them hackers but developers.
