The problem with the training academy though, that isn't just financial - the governing board (presumably the RFU) said this...
"Wasps' relocation to the Midlands is purely for matches and should not come into conflict with the Academy systems run by other professional clubs in the Midlands - champions Northampton, Premiership rivals Leicester and Championship side Worcester, who opened a new regional development centre in the city, at Broadstreet RFC, in May."

That seems to directly contradict the idea that the council and Wasps are trying to sell, that they're moving their academy and training facilities up here. Even if they had the cash, it doesn't look likely that the RFU would let it happen.
To me this is just another example of someone spinning a line, and the council buying it because it suits them.
