If they´re launching sometime next year, it makes sense they´ll be shown in some form this year.
Remember the PS3 and Wii had their first details revealed at E3 2005, then were released November 2006..I can see the same thing here...first details at this year´s E3...then a complete reveal (launch date, price, games, etc.) at next year´s E3, then the launch around October/November 2013.
