Price and availability have not yet been announced. B&H Listing to Notify when in Stock I bet somewhere around $600 USD. Canon offers the 85mm f/1.8 non stabilized that is a staple in many budget photographers bag- it is a decent lens, costs just $369 and while it suffers from some serious chromatic aberration wide open and it certainly could be more contrasty - it is under $400. I do think this new Tamron will be noticeable sharper and of course offers VC. I am not convinced that it will see well though. Nikon offers two 85mm lenses - an 85mm f/1.8 for $469 and an 85mmf/1.4 for $1560.
Tamron 90mm f/2.8 SP Di MACRO 1:1 VC
And the Updated 90 f/2.8 Macro - I am a bit surprised- their current 90mm Macro is a great value and holds up well against the competition - see below for the updates to this model. 
- Canon EF Mount/Full-Frame Format
- Aperture Range: f/2.8 to f/32
- One LD and Two XLD Glass Elements
- eBAND, BBAR, and Fluorine Coatings

- VC Image Stabilization (updated with accelerometers)
- 1:1 Max. Magnification, 11.8" Min. Focus
- Rounded 9-Blade Diaphragm

What has changed from the previous model? Sounds like optically it is going to be the same but you now have an improved VC system, the new cleaner look Tamron has used on these lenses and the TAP-in console compatibility.Price: Preorder from B&H Photo or Amazon for $649 (available in Canon, Nikon and Sony A Mounts)
Tamron TAP-in Console
The TAP-In console sounds very similar to the USB dock offered by Sigma. It acts as a lens mount with USB connection to your computer. Mount the lens and open the Tamron software will allow you to update firmware and further customize the lens. No word on price - should be available starting in March. B&H has a listing
