Any chance they still play on tuesday 23, depending on how (pre-sales) go for the tour opening? or is there a theatre show to be expected before the play the fleet centre on friday?
They will still play on the 23rd. What will most likely happen is that the 23rd will go on sale Saturday after the 21st sells out and my guess is that means there will be no presale for the second show. U2 did this when they sold multiple dates.
