Ahh, but he's not just seen them - he's excited. The question is, is he a hard man to excite or does he get worked up about any old tat?
One thing about Joe, he's ambitious. He is very serious about what he wants to do with the city. He's very keen on redevelopment and new investment. He wants Liverpool to become the second city of the UK again, and everything he does is driven by that.
I'm not trying to campaign on his behalf here, none of that means he will actually be able to deliver on anything. I'm sure people can make their own judgements on that. The point is, that it is in his interests for this issue to be settled once and for all, but if we were proposing to put up a tin shed with a leaky roof, he'd never let it stand. In that context, his "excitement" makes a little more sense, and can probably be taken as a positive sign.
But I think we've all learned by now to wait and see what actually happens. I'll believe it when it's open and tickets are on sale. Until then, probably safer to keep guessing.
