No one has them as far as I am aware... The QBP (distributor) website shows the 120tpi version (700x38) available in April and the 260tpi version (700x36) available in early Feb.

I've been Checking with a couple of distributors and the last I've heard was mid-May. QBP is showing May 1, but that'll probably change on Monday.
