2012 MBA with Bootcamp

I currently have a fully loaded 2011 13" MBA. I run only windows and love the MBA hardware. The whole ata only in windows really annoys me and i can't give up sleep mode to get proper drive support. That being said with the 2012 MBA are there inpovements with the windows drivers? I believe that on the new mpbr machines the drivers are better.

Also how is the windows boot time on the 2012 MBA with Bootcamp?
