Given that Nintendo announced the Wii U before E3 last year, and that it won't be out towards the end of this year, and Microsoft and Sony said nothing about new consoles, both having big games coming out next March and further into next year, with both pushing tablet/vita connectivity as the next big thing.
I think that at most we will see one console (probably the next box) by the end of next year but not both.
Even so, I don't think that's likely
