Correction, the club aren't telling us anything about anything. In fact we find out news about LB from other clubs.

Kent Teague for example?

In truth, Broncos need to be a fixture in SL to have any chance of success (however that is measured). So new investment/owner would have to go hand in hand with changes to the SL structure. There is no point in Broncos being a Championship team.

So lets say a new owner comes in with very deep pockets, with ability to buy a squad that can compete in SL, why should SL or the RFL change the structure to allow the London team in! What makes london any different from say Toronto who had to work up the ladder.
Catalans could be used as an example of how that could work, difference with Catalans is they have a core of supporters that are Rugby League through and through Thats not the case for london or Toronto or the other areas of expansion in recent history.
Maybe its time to accept, unless there is someone willing to step up with a fat wallet that part time is the only real way that the club will survive. That would not necessarily mean the end of the club, would be intersting to see how many of the current support base would continue watching though.
SL will and does cope quite well without a london based team, the m62 corridoor fans will keep watching those coridoor teams!

Said it before, the only way RL will ever have any chance of real expansion it would need a total shake up with regional teams, that is not going to happen in a long time if ever at all.
London has lasted probably 39 years longer than lots expected, can it make it to 50? Is RL ever going to expand to become a national sport? Not in my life time.
But on thread, exciting news! Would a new home and owner in leyton be such a bad thing? Might be best the only thing to ensure survival

The question to ask is. Can Super League survive as it is currently?
With the TV deal being up for renegotiation, what form the competition will take depends on the outcome.
With little interest apparently, from broadcasters it may be a tough sell and the resulting financial fallout might be severe.
The possible return to a semi pro sport, is a possibility.

Time to resurrect the London Phoenix idea again?
Long term plan, start small and build up. Out of the ashes of the Broncos........

Hope not but the future isn't looking too bright for the game in general is it?
