HTC Touch Diamond launching on Sprint in September for $299.99?

It won't be the first launch in North America -- those honors go to Telus at this point -- but Sprint won't be far behind. A pretty believable new slide deck suggests that big ol' Number Three will take delivery of its Touch Diamonds in September and start hawking them for the princely sum of $299.99 on contract after rebates, netting customers a 3.2 megapixel cam, 4GB of internal storage, and EV-DO Rev. A, among all the other spoils that only Windows Mobile 6.1 can offer. Is the back end of it red? Can't really tell from this angle, but if the goal is to offer up a high-end business tool, we've gotta believe black will be available either way.
