Right, MHL via USB then HDMI out to tv.. interesting idea.

Good points regarding mass adpotion!

- Large mass of ("n00b") developers adopt Google's Game Save Profiles
yeah this is still very new, google play services is new

- Adopt a gamepad standard in Android
Android has gamepad support from 3.2 I think but not in NDK that's around 4.0 I think.

- Adopt Google+ integration (PSN/XLive competitor)
from google play services: Create competitive and cooperative experiences using Google+ Circles and auto-matched players online.

- The quality of Games increase substantially (no more "App Pause" because of memory management, no more FCs, no more sub-par experience)
gameloft make some pretty impressive games, with network multipler and for less then $10, the shield, mojo it's just the start of high end android gaming!

- Piracy is dealt with much better, purchases increase substantially
from google play services: Optional anti-piracy features for Android can disable game services for titles not purchased from the Play Store.

- A good hardware matches good software at good price with good marketing
True, HW will get cheaper over time, and the SW will still work.. not like consoles!

- Mass adoption of said hardware, and its cause to add competition to the Android Console scene.
I think it's already happened with 2D touch games.. the next I think will grow is high-end 3D gaming

It's interesting,
I see the Ouya as the Atari(1977) - wasn't the first, but got it popular
The gamestive as ColecoVision (1982) - completely different
The NVIDIA Shield as the Vectrex (1982) trying to do too much

The mojo as the Nintendo (NES) (1983) - great HW & SW (high end android games)
time will tell what happens with micro-consoles, I guess it'll take off... google play store isn't going anywhere!
