They will probably do like they did with Akon and Mac Miller: Use either a day old showing (Akon) or a tape delay (Mac Miller) as neither of them were live.
So, they have a concert in September which may be the only thing they can pretend to say is his concert.
But, I do not see, as you said also, a concert anywhere in that time. I think they are leaving that on their website to give some people hope of an upcoming concert so they can still hold long shares. Just IMO.
