Chasing in HD - When are you planning to switch?

Thank our government for the hesitation in establishing broadcast standards. It ended up being a good thing, though... dragginging on into the digital revolution.
Japan has had broadcast HDTV for quite a while, but the standard is analog, and it will be a costly and difficult task to convert their existing sysytem to digital.

It really is amazing how slowly the HDTV technology rolls out.
1979 - Initial concept
1988 - US design
1993 - US standardization
1998 - US production
I'm wondering if the space on a MiniDV tape is used faster with the higher per-frame size that comes along with the HD format.
Basically, does a 60 minute MiniDV tape last 60 minutes?
