If sales keep relatively stable over the next few years, then it most probably will overtake the last generation.
However, it is to early to make an accurate prediction. It could go either way at this point. There are a few reasons for this:
Price of HD consoles- The price of the Playstation 3 and Xbox 360 are much greater compared to both the PS2 and Xbox. This could drive many people away from The HD consoles.
Shortages of wii- As mentioned above, the price of HD consoles is quite high, so some consumers may prefer to choose the wii. However, There have been many shortages of it around the world, and is extremely hard to find. This should cause some consumers to stick to their PS2, or buy a handheld system.
PS2 still going strong- Sony's PS2 is still being supported by many developers and is still selling decently. Since The PS3 has already lost sony millions, they still need the PS2 to help them regain their losses. Sony intends to support the PS2 in the years to come. It already has an established userbase, and has been able to compete with next-gen systems. How long Sony intends to support the PS2 until it pulls the plug could prevent Next-gen systems from selling as much as it could.
But as previously mentioned, it's still to early to make a accurate prediction. It could go either way at this point.
