I don't think this changes anything in the real world - Salford, Wakey and Cas got their franchise last time round on promises of ground improvement or new stadia. Salford of course are confirmed moving, so that leaves Cas and Wakey.
We all knew then that if we were neither in a stadia, or actual tangible building work happening and a road map to completion - we would all be out on our backside and that still stands. So, the equation hasn't changed - with the exception of the brief dalliance over a possible share, then situ now is exactly as was the day after we were granted a franchise.
The only way I think we can stop BOTH clubs being outed in lieu of Toulouse and Widnes is BOTH building a stadium - if neither get theirs built, then I think we could seriously be in danger of losing both from the top flight...... Which is why I think Wakey were too quick to dismiss share discussions and studies, becuase now it is a straight foot race to pour the first concrete. I don't believe the WF economy will support 2 multi million development projects 3 Mway junctions apart in the same year - look at the funding hole and problems finishing the Wakey shopping centre?
So - this is now simply whoever lays a brick first wins in my opinion without bias towards either club.
