It seems unlikely.
Smallville continued into Season nine but that's because we were two seasons behind before and the series is already well into its series finale back in the States. Dexter for instance also had a season finale last Monday but for some strange reason they decided to start from the very beginning again.
Australia was nearly up to date with Fringe and then GO suddenly pulled it off.
I don't quite understand why we have to be so far behind America. If fans have to wait too long, they'll watch online and/or buy the DVD (which happened with this season of SPN). I doubt TEN would want to lose money but I think SPN isn't very high on their priority list.
Frankly, I don't even watch TEN anymore, only ELEVEN. Seriously, what is there interesting to watch on TEN? All the American shows moved to ELEVEN and I would not want to watch Master Chef, Idol, Biggest Loser or whatever
