If they did then Dsat and TW are probably the only two viable domestic realtime platforms. The standard BBC broadcast via analogue, DTT, Dsat and cable will be using the 16:9 world feed and probably some local material filmed by a BBC crew. I do not know if HBS will be filming exclusively in HD (1080i) and down converting or using two sets of cameras.

HBS will be shooting in 16:9 1080/50i as the main host-broadcast feed. The feeds provided to rights holders are 16:9 1080/50i, with 16:9 576/50i and 4:3 576/50i down-conversions also available I believe (and I believe different 4:3 ratios can be requested by different broadcasters - so letterbox and full-screen can be provided?) I don't know if all feeds will be available in all flavours in all areas - as often there are upwards of 5 or 10 different game feeds provided at large events, with different ISO cameras, replay channels, a couple of different game event mixes (with different run up and post match content etc.)
They are NOT dual-covering in both HD and SD - the HD is being downconverted for SD clients, rather than there being a separate SD operation. (I believe this was actually the case for Euro 2004 as well, though sourcing the HD, or even the 16:9 SD feed, was more difficult at the IBC?)
If the BBC DO decide to take the HD feed from HBS, then I suspect they will also do their location presentation in HD, or upconverted HD from SD, so that there is a single BBC One feed - with the HD version going out on BBC One HD, and an SD downconvert on the current BBC One outlets.
The Beeb have got to get used to doing location presentation in HD, or if not doing this they have to handle mixing HD and SD feeds, and now is as good a time as any - though the World Cup is quite a high profile event to trial new techniques I guess. (On the other hand they've been working in the background with a lot of HD sport for a while... Quite a lot of events screened in SD are being shot using their HD truck, and HD recordings made at the same time)
The Beeb are planning to trial an HD "Freeview" service in London only, as part of the BBC One HD trial, but whether this is running in time for the World Cup, and how many receivers will be available for trial participants is another matter. (Though if they are FTA DVB-T broadcasts then PC owners with DVB-T cards and fast processors capable of H264 HD decoding may be able to watch as well I guess?)
