I do believe so. If I recall the 2004 Sienna already has fold in floor seats. No, I believe that Toyota is saving that underflow space for equipment associated with the expected hybrid drive sienna. The second row seats do not fold into the floor only the third row seats. Underneath the second row seats is the spare tire.
The 2005 Toyota Sienna has 43.6 cu.ft. of cargo capacity with all of its seats in place.
According to my Toyota dealer the answer is yes. That is why I have a 2005 XLE on order (I was waiting for 2 power front seats). However, even though they are now making 2005's in production, I can't find any more information about them.
