I would like to see Finding Nemo or Star Wars Episode 3 in WM9 format, directly from the digital source.
I can't play the T3 version on my HTPC at the moment, and I am loathe to upgrade it for just one film. However, if they bring out more titles in this, I might just. They will have to sort out the licence system first though, being in the UK it took me a while to get a licence to work.
It's the only way us brits can realistically get Hi-Def at the moment.
