In the finer print, the pass stipulates that all games you can play must have been originally priced at $30 or less. Additionally, all games are not simply available like they would be in Netflix or similar services, you still have to "buy" them at a price of $0.00 by looking through the catalog and selecting each game. All in-game purchases do not have their prices discounted.
The new Pass is available for a limited time only as OUYA continues to test new models to stay afloat.
Recently, the company discussed creating an OUYA SDK for use on set-top boxes by OEMs and also on HDTVs. So far there have not been any major developments on that front.
