They've said it won't be televised, very clearly.
They could backtrack but that wouldn't be cool.
They may of course release something down the line as the gigs will be filmed.
That could be one way of appeasing the fans after the farcical ticket sale.
Regardless of how Oasis try and sell any further tickets for more concerts, the same people who got tickets for the 1st concerts will try and get tickets again. There will never be enough tickets to meet demand, no mater how many concerts Oasis perform.
At least with 1 televised concert millions of Oasis fans will get the opportunity see them play live, albeit on the TV. It will never replace being at the concert, but it’s better than not seeing Oasis play live at all.
