I checked today ticketmaster and the O2 arena site and there are still tickets available...
We are guessing that there will be Royal Albert Hall dates because it happened like that with Tracker tour too, and there are some big gaps in the tour schedule but last time we heard from Guy that there will be some more before it was announced, this time we don't have any single clue about any real chance of Royal Albert Hall dates...
However, MK gaps and RAH gaps coincide:
MK availability / RAH availability
20-23 May 21-22 May
31st May - 6th June 31st May - 5th June
If it's going to be any RAH date, I bet the 31st of May and 1st of June, just after Birmingham, same that happened with Tracker tour.
