Last year, prior to the 2010's release, there were a few Toyota dealer websites that had preliminary specs that were pretty close to what was released.
Doing a Google search, I found that those dealers have entries for the 2011 model year. An example is
here.
The pricing is obviously copied from the 2010 listing, but if you review the specs (and compare them to the 2010 listing on their site), there are several notable differences. I noticed the following:
- Transmission remains a 5-speed
- Demise of the 4-cylinder model. Not listed on the site. No V8.

- Leather steering wheel added to the Trail Edition
- Limited wheel width shows 7.5" (vs 7")
- Memory seats and cargo cover added to Limited standard equipment
- Antenna shows "window grid" -- this one is questionable, though, as the 2010 listing on their site also shows "window grid," and we know that's, unfortunately, not true.

This is all pure
speculation, of course, until the real info is released from Toyota itself (probably September to the public?).
They also have 2011 listings for the Highlander, in case anyone is interested. It's a mid-cycle refresh year, but I didn't notice much besides new colors (including Shoreline Blue) and the 3rd row is now split 50-50.
