Looks like the new NEX7 successor the 7n will be announced at a Sony event next month and should be available by May.
"Trusted sources told us that the new NEX-7n is going to be announced in one month and it will be available in stores by May. The new NEX-7n will look almost the same of the current NEX-7 but feature major changes inside the body. Every aspect has been improved and the main goal from Sony was to outperform the top MFT model like the Panasonic GH3 and Olympus OMD. Sensor, viewfinder and autofocus have been improved. I am working on the specs right now. And there may be some new E-mount lens too (like the Zeiss zoom)."
And it also looks like Sony is finally getting around to releasing some more native Zeiss E-mount glass. So if your looking to get into a compact system you might want to wait a couple months.
