At this point I'm starting to think if we don't get an announcement tomorrow or the day after we wont get the single until September. Leno isn't exactly a place you make a big announcement so I've not got my hopes up for that and Gaga has the later half of August on lock down.
Really hope she doesn't try what they did with Part of Me and announce it only 4 days in advance, there needs to be at least a week or 2 of hype.
