I'd be quite amazed if that happens. Considering that NCT couldn't make it pay despite them being a well known name, and the flop that Premiere had, I really can't see how Trent can make a go of it unless they extend the route beyond EMA to another big catchment & I don't believe that exists around EMA!
I've been musing over these points myself. The only things I can see are different are:
The old NCT service was a tendered service for Nottingham city council. It was withdrawn when TB started their route. The reason given at the time was illegal competition against a commercial service. This was questioned at the time since it was an entirely different route, serving a very different market, and was likely a political move.
Premiere got a lot of things wrong, and paid the price. Red flyer was a pretty ropey service, didn't need to undercut TB's fares and didn't need to be 24/7.
Virtually no one uses Skylink Nottingham to travel from Nottingham to the airport, most flows are Nottingham - sawley / m&s then Castle Donington - airport. The direct market is pretty much unserved. I'm not sure how big it is though.
The A453 has had a few quid spent on it recently.
Based on these facts I can only see two real possibilities:
One of NCT's Clifton services gets extended, possibly via Gotham, East Leeke and Kegworth, effectively doing the tying up local routes thing. Or
TB ( or someone else) operates a "Skylink express" on the old route, probably focusing on daytime only, commuter market which could pay off.
