In advance of the Musikmesse, u-he has sneaked a peak of the Satin “authentic tape simulation and beyond” plug-in for Windows and Mac.
Urs Heckmann on Satin:

Basically… Satin is not just a tape emulation. I’m thinking of it as “all of tape”
Without being modelled after specific gear like Diva, Satin still has a mix and match approach. There are various pre-equalisation and post-equalisation curves to choose from as well as various noise reduction techniques and a choice of tape speed, plus a few head/gain adjustments. The sound of tape ranges from subtle to drastic. The adjustable noise level is irresistable.

u-he’s upcoming tape emulation plug-in Satin: Will It Blend?
Satin features

• Continuous tape speed control from 7.5 to 30 ips.
• Saturation with realistic bias and hysteresis, wow & flutter.
• Rec/repro equalisation, selectable industry-standard curves.
• Tape delay with up to 4 repro heads, on-the-fly flanging.
• Head adjustments, various coating formulae.
• No squirrels or other rodents inside.

Satin is expected to be released in May, 2013.
 
Look very interesting!

Looks like it is getting closer, I know it was pushed back after some tester feedback.
 
Will be interested to try it out.

Looks interesting, but for me will depend a little on the price  -I have ReelBus and Magnetic already so this would have to do something very different (which I think it might reading the specs). I do use Reelbus and Magnetic, but not all the time.
But end of the day, price will probably be a main contributing factor. Hopefully also a demo - I received an email about Sugar Bytes WOW2 which looks very interesting, but there is no demo, so have not thought any further.
