The Thermalright T-rad2 is coming hitting stores in September
there will be 2 revisions of it - for new nvidia cards 260/280 and another revison for normal cards (8800GT/38x0/48x0/X1x00/7900)
It's a single-slot solution and can only be mounted on one side of the card (gpu side) not both siides like the hr-03

-from thermalright

I personally dont like it more than the hr03 since it has a higher fin density, meaning it require higher cfm, which means more noise
