With the Wii we saw a pretty consistent 5m fallout after  2009, that did not begin with the Wii U.  Mario Galaxy 2 & Donkey Kong Country, Sonic Colours, XenoBlade, Metroid Other M, Red Steel 2, Golden Eye and more didn't stop Wii's decline. 2010 was a significantly better year than 2009, but 2009 had Wii Sports Resort,  Wii Fit and NSMB. Its not about the number of games released but about their ability to attract new audiences. 

Or rather, attract old audiences they had lost at that point imo.
