I bought the DVD of last years too... Bit of a waste of money to be honest! The 6 TV episodes were much better! Not only that, but there are loads of clips floating about on the net which have a load more of the action compared to the DVD.
I would imagine it will be a while still before we see any of it on tv. Tbh, you'll probably be able download a lot of the footage before they all get put together and shown on TV.
