I think Paddy's have made Entourage favourite as a default because it won the International Award over at the Royal Television Society awards (albeit against two other programmes that are fairly obscure at least to mainstream viewers anyway).

The other television awards to note is the Broadcasting Press Guild awards.

Both have a terrible record as to their winners becoming BAFTA winners but I'm willing to take a chance that a few RTS winners foil the 'obvious' picks like Jim Broadbent and The X Factor.
I'd be surprised if Stephen Merchant who's won almost everything he's been up for in the last year falls at the last hurdle (he won Best Actor ahead of Ricky Gervais at the British Comedy Awards gone by).
