First of all, Myles apparently said "I think it's called Isolation" he doesn't sound too certain himself.
I'm just gonna copy and paste my response from ABB.net (I said this in response to someone saying "well if Myles said it, it has to be true")

Not really. The band (Alter Bridge) has said the Deluxe DVD would be out in "insert month here" but we still haven't seen it. I remember the days when the guys were saying Full Circle would be Creed's first single from Full Circle, actually, remember the days when Mark said Creed would never reunite?
I wouldn't treat it as 100% legit until we actually have an official announcement.
Your title is misleading, it is not the new single until it is confirmed to be. Myles simply saying "I think it's called Isolation" is not a confirmation. Isolation could well be the single, but for now, we can't be certain.
EDIT: Sorry, can't get the link to work.
