hmm, would hope it'd be higher than 50k myself. I'd be ok with the possibility to expand based on success and get the success first before looking for bigger, because, well, Cardiff down here look like right clowns deciding (after a single promotion) to double their main stand and now are struggling mid-table in the championship with not a massive amount of money, after being relegated straight away from the prem.
I know the income we get will be much more than "just 10,000 extra seats", because of the massive amount of extra corporate boxes and sponsorship etc. But still, bigger capacity is more important to me.
But hey, all estimates atm, it's still a very good day.
