I've just logged back in to see what's happening - one session, connected within 30 seconds, and I would say the numbers have gone down all that much since I got my tickets at 10 to 8 this morning. I'm in block 550, which is showing as 'good', I'd estimate about 150 left in that block. There's 4 full blocks and 2 smaller blocks showing 'good', 10 full blocks showing very good, and 5 blocks showing limited. It would seem that based on how easy it was to get connected, the majority of '5s' have bought theirs now. I don't want to get hopes up too much, cos this is only my opinion - but I'd say 4's have got a good chance - even if it's on first come first served.
