From Sprint's BAW forum, poster Tristan, a Sprint Admin who accurately foretold the coming of 2.16:
I do have confirmation that the 2.16 ROM was pulled from the HTC site. I don't have a date (official or otherwise) for when a new update would be released.
As always, when I have any information I'll be sure to post.
