What I think will happen is we will go to WSS for a couple of years and than move back to ANZ Stadium after 2020.
What people seem to forget is ANZ stadium is being revamped (with the largest financial contribution by the state government out of the 3 stadiums) and if my memory serves me right, they will be converting it to a dedicated rectangle stadium with state of the art amenities. When ANZ is finished the seating will be much more vertical than it is currently and will be a large version of WSS with capabilities of adapting the stadium to small, medium and large crowds so the atmosphere is not sterile no matter the size of the crowd.
They have committed until the end of 2022 at WSS. Maybe they will have 4 at WSS, 4 at ANZ, 1 at LO, 1 at CSS, 1 at Tamworth and just for a change 1 at a mystery ground where fans will have to pre purchase tickets without knowing where the game will be - they will then be bussed or flown to the mystery ground for the game. The upside to this is the opposition fans won't know where the game is at so the only supporters at the ground will be Wests Tigers fans. Might suggest this to Pascoe.
