Dates for 2012 Prius, and will the Plus package still be offered?

While the final release date for the 2012 Prius is still a matter of speculation, due to current 2011 inventories, I was more curious to find out if, when the 2012 comes out, the Plus package will still be offered? I want to get the 2012, with the Plus package, but want to make sure that configuration will be available by the end of Q2 2012. Does anyone have any slightly inside information? Also, does anyone know if the color selection for this package will be broadened from BP, CS, WGM, and BK?

Thanks and happy holidays to all my PC friends.
