I don't think it will, not because you're underestimating the Wii U or 3DS but rather because you're overestimating the PS4 and the 8th gen in general.
I think this will be a shorter gen with flatter sales curves and a significantly smaller total installed base than the 7th gen, in home consoles and handhelds (the latter being a given at this point) and I see no reason to think that anyone will be able to repliacte the PS2 now or any other generation ahead.
