I really, really hope it's the HoT too!
I too think that we'll get some really interesting sword mechanics. The cool thing is that WMP can actually detect how fast you swing the remote, which could actually deal different amounts of damage. I believe Red Steel 2 uses this feature.

I'd also like to see real "sword Fighting" up until now it was Link hits... Bulbin hits... Link hits... Octorok hits... I'd like to actually be able to parry and have a realistic sword exchange.
