No. With the gap where it is, and current PS3 sales, it would take three years of the Wii selling zero units (i.e. discontinued) for the PS3 to catch up with it. Since it will overlap with the Wii U for at least a couple of years, however, and it's still selling very well, I don't see an immediate discontinuation. It's not impossible, and arguably stranger things have happened this generation, but it's highly unlikely.
