According to info from April and May, there will be no Stargate Universe movie, no Stargate Atlantis movie, no more SG-1 (but we all already figured on that didn't we?), and the entire fate of any more Stargate of any kind is unknown. Syfy seems entirely disinterested, the creators/writers seem fed up, and MGM could not afford to continue it even if it wanted to.
Or at least that's what's been said so far from TPTB.
My idea of British TV probably would not work because over in UK, a normal season is 6-8 episodes of 45 minutes, while a "long" season (like Doctor Who) is 13 episodes. So even in that best-fate scenario, it would be a much shorter show.
Oh well, good while it lasted.
