Xbox 720 and wii 2 to be here before 2011?

In a recent "wiids" podcast, the hosts mentioned an reliable source, had told them that a fix was on the way for the wii in terms of memory and graphics, and it would be on the market before 2011. Could this mean that the next generation wii is only a couple of years away? they also mentioned that the next generation Xbox would be out by this point.

This source may be reliable or it may not, but the hosts seem to trust them alot. The show may seem small and under developed, but they have had square employees on in the past and a Konami games writer.
