looks like they are shooting for September 2010 launch, which is 1 year after the slim was launched.
They could be going for another price drop with the launch of the "Arc" or a cheaper bundle.
If you ask me its a better plan, because now the software lineup should be even better, they will have more time to hype it up using the media, momentum going into Christmas 2010, and a big blowout at E3 2010.
Sony might even be able to drop the price of the PS EYE by then to $25, being able to offer a cheaper bundle with the "Arc."
