I would hope any future box from Virgin played more to their strength in massive bandwidth to their customers than in huge numbers of tuners and local storage. Watch from the beginning and letting customers build cloud-hosted programme libraries out of recordings, on-demand subs and purchases would give them a better competitive edge.
This from Wired a few months back is good on the problems of making a decent set top box:
