I am trusting the club that they will come up with an internal design that maximises the noise Goodison can create for a big game, but also considers the fans wishes in the survey they conducted. With regards design, I think the drawing that we have seen is probably not far from the final design but there may be some surprises, hopefully including the capacity and plans for the area on non-match days. If you look at the rendering next to Robert Elstone, you can see the wind turbines that already are in situ at the dock. Looks like some red brick forming part of the exterior stadium, possibly reflecting the brick work in the Tobacco warehouse, Titanic, other warehouses etc.
It seems odd to me though, that with all this being so secretive, Robert Elstone would be showing off renderings in other continents that are current. Likely earlier drawings and maybe a starting point for the final design.
In all honesty though all I care about is it being at the dock in a prime location. An iconic stadium that is the envy of other clubs would be marvellous, but considering we almost ended up in Kirkby even transporting Goodison to BMD would do me. We have to be part of that waterfront or we will never make up the ground we have lost over the last 25 years. Build the stadium and maybe somebody richer than Moshiri will arrive that can make us truly a force on the field of play. It happened to the Citizens, it could happen to the Toffees.
My biggest fear is that "...we couldn't get it over the line..." or "...finances transpired against us particularly with Brexit that meant the stadium was no longer deliverable..." If that were to happen I cannot see Everton solving this stadium problem, ever.
Things have obviously slipped on the timeline but the complexity cannot be underestimated. I have a feeling we are almost there, but won't be truly happy until there are diggers digging, cranes lifting and foundation stones being laid.
