That ties up with a thought I've had recently. Well two thoughts really...
i) The WSU seems too cheap. It was the most in demand section of the ground in the initial sale, and it's far cheaper than the ESU.
ii) Why isn't the front of the WSU more expensive than the back of the WSU? I'm lucky enough to be front row and my view has to be better than the back row, surely. I'm also only a few feet above the premium 'best in the house' seats in the WSM.
(I've got no reason to believe that anything will happen with prices relating to these points but, again, it's something I'd probably look at.)
Can you imagine the chaos that would cause? or do you just expect everyone to stump up for the increases?
Personally, I think a lot of people, like me, chose WSU because it was cheaper.
I think significant price rises in WSU would see a lot of people giving up on their STs altogether.
