I don't think this series will go past Season 1 to be honest. The way the last few episodes have come out in drips and drabs, suggests they are using the last remaining episodes as a "filler" when they have nothing else to show. They wouldn't do that if the they were giving the show another chance with a second season.
We will see the last episode aired, the question is when.
On a side note, probably deserves a thread of it's own, but I was just on the ABC America web site looking for information on the last episode, and they are advertising this new series which looks pretty interesting. It's called "V".

Apparently Channel Nine will be showing it at some stage according to Wiki.

Have to look out for the pilot at all the usual places this week.
