2009 Sienna any idea when?

I love my Prius, but I need 2nd vehicle for our family car with 7 or 8 seats to accommodate our grandkids. Yes, I have a 2002 Suburban. It stays parked most of the time now with gas prices going up. I have kept it to haul business products several times a month which will not fit in smaller vehicle.

I sold our 2005 Murano to our single son, since my wife wants a minivan. I am considering a Sienna or Odyssey. However I would hate to buy 2008 if the 2009's will be out soon. It doesn't look like a Sienna Hybrid is coming anytime soon.
