If you are talking about the PSV and PS3 versions combined then this might possibly come true at some point down the line, but I doubt it.....if you're talking about just the PS3 version though, then I disagree. I'd say 1.5-2 million at the absolute max.
My prediction threads:
Wii U will sell under 40m units (made on 14th September 2012)
PS Vita will sell under 20m units (made on 30th September 2012)
Wii U will sell under 7m in 2013 - I was right
