It's official: I have a contract for an XNA book now

Yesterday I signed a contract with Wiley Publishing to deliver an XNA book under their Wrox imprint. The title is "Expert One on One: XNA Game Programming for Xbox 360 and Windows". Quite a mouthful, I know. Despite the name, it's a book for both beginners and experts, but the Expert One on One series works best for my writing style. The book should be out this summer.
