I think we may possibly see an Italian route from easyjet, possibly VCE or NAP, maybe served 3/4 times weekly together with another eastern european routes, perhaps KRK, WAW or similar, again maybe not on a daily frequency. MAD too is a very string contender.
From Jet2 I am expecting a TFS rotation plus maybe AMS and possibly LGW?
I think Ryanair and Flybe will not announce any new routes for the immediate future, but then again who'd have thought that so many new flights would have started from NCL in the previous year or so.
Emirates to DXB would be a true gem for the airport. Maybe 3 times weekly would work, though would they only be able to use the A330 on the route, as can the A340/B777 land/take off with no restrictions at NCL?
Expect a few new charter destinations announced, maybe not for this summer but indeed for next winter and the following summer.
