I imagine that the Super Wii will be released in late 2011/ early 2012, while the 720 and PS4 will be released in the second half of 2012.
I think Sony is approaching a cross-roads, they can continue becoming first party oriented, or they can concentrated on the 3rd party side of things. This will probably help determine the console itself and therefore it's release date.
That said, even if Move moderately takes off, Sony will not desperately need to replace the PS3 with a successor for a couple of years.
