Nah, not seeing it.
That said, I DO see the gap that we saw between the PS3 and DS being shrunk down to PS4 and 3DS.
The 3DS long term falling short of the DS by 10 - 20 million lifetime wouldn't surprise me, while I feel confident the PS4 will gain significant ground in the US while maintaining dominance in Europe. Japan could either go a few million less or a few million more depending on a few factors. I also see "other" doing better as well than the PS3 longterm, but that gets quite a bit more complicated...
The real question is how big the gap will be.
