That is true. However most new broadcast studio and outside broadcast facilities are now built using the new "3G" (aka 3Gbs) HD-SDI infrastructure that has the capability of carrying 1080/50p and 1080/60p content (not just the 720/50&60p, 1080/50&60i and 1080/24-30p content that 1.5Gbs original HD-SDI could carry)
The current high-end cameras being installed - like the Sony HDC1500s and the ThomsonGrassValleyPhilips LDK 8000s (I think) - have 1080/50p and 1080/60p output at their camera heads, and new CCU and cable tech means that this will also be available on the CCU outputs.
Similarly vision mixers with 1080/50p and 1080/60p capability are imminent (if not here already)
It WILL soon be possible for studios and OB facilities to work entirely in 50Hz or 60Hz 1080p (it's been possible to work in 24-30Hz 1080p in some existing trucks for a number of years - as is the case with some music concert productions)
Of course there is no current means of getting this 1080/50p or 1080/60p signal from the studio and OB to a domestic TV yet - as the main network HD infrastructure is still 1080i or 720p - and there are no current adopted mainstream broadcast standards for 1080/50p or 60p broadcast.
HOWEVER if you build a studio to last 10 years or so - then you'd be foolish not to consider what might be round the corner. A lot can change in content distribution in that time.
I know that the new BSkyB (aka Sky) studio complex due to open in 2011 in West London has been specified to be 3G HD-SDI capable, and I believe they are ensuring that their OB contracts include a clause that can mean that suppliers have to allow for 3G 1080/50p production at some point. (Sky are also pushing ahead with 3D production tests - and 3G also allows 2 x 1080/50i signals to be routed down a single feed as well - so there are other reasons other than 1080/50p production to mean 3G infrastructure is sensible)
The new OB trucks used by the BBC for Wimbledon this year - OB3 and OB7 - are 3G HD-SDI equipped AIUI. (Though they currently run in 1080/50i - their cabling and routing infrastructure is 1080/50p ready)
