Boats & Houses in high definition on HGTV-HD

Home and Garden Television is coming to an HDTV near you later this year, now we've found out some more of the programming they have planned. In conjuction with KPI Productions, we can expect six specials focused on "extreme spaces" like glamorous dog houses, unique roof amenities, luxury swimming pools, and the apparently booming market for "adult treehouses".
I would not previously have thougt I would be interested in luxury doghouses, but hey, put it in 1080i and I'll watch.
