I'm being pedantic but if there's 10k free tickets then hardly a "sell out".
Even with that, I don't think they'll sell the rest.
Despite the possibility of scoring a few (I still wouldn't carried away on that either though), many of the regular SSC members won't attend, although I'd concede many newbies or less regular TA will attend as more tickets will be available to them now (which is great especially if bringing their kids, nephews, neices etc for the future).
Good luck to the newer, younger fans, but the $FA has still shafted the rest of us.
