I think as long as riders want to compete it will still be around and let's face it, even if the IOM doesn't NEED the TT no sane person turns down the chance to make extra money so I think as long as there's money to be made it will continue in some capacity.

I do think the event needs a bit of an overhaul though, does it really need 3 1000cc races? Why not drop the Superstock in favour of a Junior Supersport/Moto3 race?

I like the Sidecars but I've had a feeling that they're on borrowed time for a while now, feel free to correct me but it seems like the Sidecar grid is shrinking quite significantly as the years go by as the competitors decide to call it a day and there isn't enough "young blood" coming into the class.
