From what I understand, TZ is supposed to come out in Nov (making it the next "pack", though likely to be sold by itself), and STTNG in Jan., leaving just one standard pack left. Why not wait until both TZ and STTNG are released, then release everything at once. Otherwise, we'll have a long wait for STTNG.Hell yeah!
I'm just saying if I had to guess, they'll do pack 4,5,6 + TZ in November or December, then packs 7,8,9 + TNG...maybe by like Feb 2013?
I don't know how they will do it but if they release a big update right before Twilight Zone hits and we have to wait 4 months for TZ that will be heartbreaking.
