BD only supports 50p or 60p at 1280x720 resolution, unfortunately. Although ATSC and DVB both support 1080p/50 and 1080p/60, I don't think these are currently used anywhere. Fortunately, DVB's "Scalable Video Coding" support means that older hardware that pre-dates 1080p/50 should just use the 1080i/25 "part" of the stream rather than crash or whatever. So, in theory, the switch to 1080p/50 can be made at any point in the future without affecting current consumer hardware.

I guess the timescale of the switch depends on what existing infrastructure broadcasters have in place - if they've shelled out on suites that only support up to 1080i/25 (or 30) then they're not gonna switch to 1080p/50 (or 60) any time soon, even though it shouldn't require any more bandwidth to broadcast. This is why they should've just ditched interlaced broadcasting from the beginning when HD standards were devised. >_>
