If it is Sartori taking a major role, why? What's in it for him? To me there can only be one reason, because he wants to make a real go of it, I can't see any other reason why he'd want to spend millions unless he has a plan. It just doesn't appear logical to do it if he's just going to be an absent owner still, plus he's now investing more it'll make it harder to get that money back unless we do really well.
I'm hoping he's really thought this can take off with a bit of proper backing, possibly frustrated at Donald for the mistakes and minimum investment so far. Maybe he knows if it goes well his FiL will come on board? Who knows but if it's him I can't see any reason for doing it unless you're going to make a serious go of it.
