There's work being done to add Freeview Playback; beyond that I don't have any specific information.
I would hope that at some stage we'll seen an equivalent of the TF6000, with wireless or ethernet connectivity, but they're not going to launch a UK specific model without MHEG, in my view - it wouldn't get a digital tick mark.
New models elsewhere have focusssed on HD, like the 7000 PVR in Australia and the 7700 receivers; I doubt we'd get a 7000 series PVR here, because that's MPEG2 HD, and so only really any use in the Australian market.
The 7700 receivers have MPEG4/HD, but there aren't any PVR models yet; and in any event the market for those would be pretty small - at least until the BBC Freesat proposition is up and running.
I don't know how well things like the 6000 have sold elsewhere, if there is a real market for the network access built in. That may well determine whether or not they decide to do one for the UK.
I think, from their point of view, any new UK model would just be tinkering round the edges, like adding the network access, or the better front panel displays of the masterpiece and TF5500 models, or the HDMI port that's on one of the Finnish variants.
Until Freesat is up and running, breaking the Sky box stranglehold, or there is a committment to HD on terrestrial, I'm not sure those little changes to the box would generate enough additional sales to make it worth the effort, even just of adding the MHEG code to one of the existing boxes.
HDMI - not much benefit for an SD box; most people have limited HDMI ports on their TVs, with better quality sources than Freeview to feed into it.
Front panel display/cosmetics - again, a pretty minor benefit. And the same, I think, is true of networking. Sure, some people buy the Toppy because of the potential for networking it, but I suspect the number of people who actually use the connection regularly is very small.
Are there any other big improvements that couldn't come from updating the firmware? I'm not sure that there are.
We're probably in a bit of a limbo situation in the UK as far as manufacturers are concerned; just before switchoff, no clear signs of what will happen about HD on terrestrial, and the Freesat proposition only just given the go-ahead.
Still, I shall see if I can find out any interesting news when I have the time.
Nigel.
