prolly fake, but it can happen any time....
last info from mtgox twitter about LTC is:
"Thanks for the mail.
We have plans, but not sure about the ETA now. We will keep you update in our website."
So there will be no announcements it will just pop up one morrning
Not that I believe this is a real PR, but think about it; they've put a block on it until June 9. They're not just going to admit to any random person over email of Twitter that they had a leak and that the PR is real.
