"B82", the unidentified product from Apple that could be released on Wednesday

This week jumped to the fore the rumor that Apple could introduce a new generation of Apple TV with the iPhone 3. In the internal references Apple refers to these products and other unknown so far:

iPad (in their different capacities, colors and data connections).

But this list is a new benchmark that we have not been able to identify with any of the Apple devices. It is numbered "B82" which could be related to a new accessory for the Apple TV, say several U.S. media. So this is a simple cable connection, an adapter for Thunderbolt or even rumored as connector 30 pin (smaller dock).

What are your bets?
