It is still mathematically possible; assuming PS3 has the resiliency of PS2, and it continues to sell at a minimum or average of 221,500 for 179 weeks straight.
All Sony would have to do it strategically place counters on or before the release of Wii U and its games, as well as the release of the successor of Xbox 360 and its games by form of price cuts, bundles, abundance of AAA games preferrably exclusives, and most of all, persuasive marketing. PS3 could reach 105M by Jan first or second week of Jan 2016.
Ultimately, for your prediction to come true, Wii's life would have to end abruptly to a grinding halt by the release of Wii U or several months after.
