I didn't interpret that as a situation where the previous gen will only be sold with the new model until the old inventory is depleted, but as a way to keep selling a "cheaper" Prius model. EG: I take that to mean you'll be able to buy a 2010 and 2011 (etc.) 2nd gen Prius. Not just the 2009 model year 2nd gen Prius until they're gone.

VW has been doing this for a couple of years in the Canadian market with the Golf & Jetta. You can buy brand new "previous generation" versions of those cars that are still being built and marketed as "City Jetta" and "City Golf/Rabbit" alongside the newest versions of those cars.

I think Nissan did this with its Sentra at one point as well. You could get a new Sentra, or a new Sentra Classic.
