I keep waiting for a announcement of when the next quarterly speical "The Waters of Mars" will air. Summer has come and gone and were less than 3 months away from the xmas special.
As for the best show on tv right now...nearly all of the shows i usually watch either ended last year (BSG, SG:Atlantis, Terminator:SCC) or are on hiatus (TruBlood, Lost, Dr Who), so right now the only show i'm watching is Hero's.
