I think unless you're brave, it seems to be a wait and see thing here.

ABC and SBS are 720p, and they look fine.  I do wonder about the other 
channels being 1080i.  You do notice the better resolution, but I would 
agree they'd be better using 720p for sports.  Thing is, doesn't DVB-t 
allow dynamic resolution changes, so they actually could switch to a 
progressive option for sports?

Personally, I watch vanishingly small amounts on the commercial 
channels, so it's a moot point for me.

I'm hoping my Via EPIA ME6000 will be able to take a PCI VDPAU card so I 
can have a rather simple upgrade to HD, and still enjoy a frontend with 
no moving parts.  But the card I end up choosing will need to do just 
about everything in hardware, or it won't work.

But I'm willing to wait until things settle down.
