@Dr Herbie: This guy is selling it for USD466.

This one is a known, authorized reseller offering it for USD455. Jump on it. There are only 5 left.

Or you can buy it directly from the source for USD399 (upgrade price). LOL

CALs for USD391 through Amazon.

Visual Studio 2010 Pro Upgrade is USD474 through Amazon.

(474 + 391) * 10 + 399 = USD9049

That's insanely steep, even for Microsoft.

I'd at least wait for VS2012 (aka VS11).
