Exchange 2007 SP2 in an environment running all 2008 R2 DC’s

An employee pointed out this artcile at the exchange team blog –

He also, correctly, pointed out how bad this part of the post is Windows Server 2008 R2 is “not widely available yet” – perhaps the MS guys need to be reminded how difficult it makes it for partners to push new products with stupid comments like that in a product team blog. (if its available to VL customers, its widely available!)

Anyhoo – perhaps a comment along the lines of “Exchange 2007 will support environments with only R2 DC’s within 60 days” would be less damaging for the product?
