I'd hope the poll is just window dressing by the club really.
I'd expect them to already know exactly what they want to do and have a business plan in place for it - especially for elements such as whether its standing or all seat and whether it'll be part segregated!
If people vote for the different elements of their plan they'll present it as satisfying fan's wishes, if they don't they'll just ignore it.
Only bits that might have been open for debate are things like food concessions I'd have thought - and that looks to be heading down a predictable route (I voted like Emma though

).
I'd be pretty certain that there will be a decent increase in cost for a segregated middle section though.
