You should be able to search the topic. I'm not sure what forum I was reading but it was a general consensus that the components were not installed (based on ifixit's teardown) and that it was unlikely that video output would be capable. I'll try and find the thread for your viewing displeasure.

I'm not sure offhand of this forums rules, but in an effort to be compliant, this is how to find more technical information on this issue. Go to the world largest developer forum and search for the topic "TV out via MHL yes or no"

I returned a tab 2 7.0 so that I could pre-order the Nexus! I also have the Galaxy Nexus phone and I flashed jelly bean on it. I must say that jelly bean is unbelievably awesome! I could care less about taking a photo with a tablet. I'm ok with no sd card because I had a defective one burn up a phone once. Back up to Google drive for storage and you won't ever lose your stuff! And with a display as close to retina as you can get and you have one heck of a deal!
