ordering 2009 Prius or waiting for the 2010?

I would like to buy a Prius but do not know if I should wait for 2010 or order the 2009 now.

Here's my situation:

I am not in a real need to get a car until September 2009. Even if I were to get a car, my travelling will be less than 8000KM for the year. Most of these routes will be covered by buses so I can survive without a car. Next year this time however, I will do a lot more travelling which makes a car necessary. I must get a car by Sept 09, so the timing of the availability of the 2010 Prius will also be important, too.

Here's my understanding:

2009 will be a really stable model, but the resale value might be affected (another post suggested it wouldn't matter).

2010 might be relatively less stable and also at a higher price but will "look new" (thus better resale price) for a next little while.

Here's my question:

I would really like to get my hands on one of these cars. However, with the new redesigned model together with new hybrids from other manufacture, I am wondering if I should wait and see how well each of them will perform or jump right in and get the 09 now.
