NEX-6: Shutter speed when making video

Since you're shooting video . . .

I'd be very interested to know how it handles recording 1080 50p/60p for extended time periods. Previous NEX models were notorious for overheating - often at around 10 minutes or thereabouts.

If you get the chance to do a test, I foe one would be very interested. I'm ready to but the NEX 6 - but I need to be able to get at least 20 minutes of continuous high resolution recording - or I'll be going with one of the Panasonic models (probably the G5 - or maybe the GX2 if/when this comes out).

Thanks!
