ePhotozine has a review up on this lens now. Their only gripe is the price, which frankly seems to be all over the place. In the US it undercuts the Canon MKII by about $700; in Europe the Tamron's suggested retail is higher than the Nikon, Sony, and Sigma versions and is only cheaper than the Canon (but not by much).
Tamron dodged a bullet with the 24-70 VC because Canon's price came out so much higher that it made the Tamron seem reasonable despite being hundreds higher than the Sigma equivalent and because Tamron had a killer feature (VC) that the new Canon didn't. This lens may be a harder sell if they don't bring the price down. It's only advantage at the moment is being a bit lighter and more compact. AF is still not as fast as the MKII, so...I would expect to see the US price more like $1350 within a few months. I doubt too many people would choose the Tamron over the Canon if the price was even just a few hundred difference.
Comparing their review of the Tamron with their review of the Canon, it seems they're suggesting the Tamron is optically superior.
