Thanks to bistokids for alerting me to this interesting line from The Independent.

Hunt is slightly less of an amusing anachronism than he used to be, and people have more of less worked out that the full truth will always be unforthcoming (especially since another series of Life on Mars is also planned).

A journalist that got their wires crossed, yeah? Matthew's blog post was a very happy "thank fuck that's over", Phil's said he'll be sad to see Gene go, but needs must. So this couldn't be true. Matt and Ash always 'planned' to have three series of Life on Mars and this is where the discrepancy lies.

Imagine a world in which this would be true, though. Several thousand fangirl hearts would explode from glee.
