LG announced the  LGBH200 Super Blu Player for watching both Blu-ray and HD DVD discs earlier this month. It'll cost $999 when it ships in October.

Apparently, the LGBH200 will have HDi support, 1080p output at 50/60Hz and 1080p upscaling of standard DVDs. It will be able to play audio CDs, and go online for bonus content. It can also access a full set of Blu-ray interactive features-where available.

This is however one of a slew of multi format players coming down the pike, there is one from Samsung at a similar price sporting both the Blu-ray and HD DVD  capability also.
This is a trend I think that will continue until one format finally wins out, (if it ever does)and given that increasingly these disk formats support greater functionality in their second and third generations of interactivity- ie the features that users can access when driving menus and controls- it seems nuts to bank on one format.

Would you ever want anything that cant play both?

Damn. you know how early one has to get up to get onto the 6am out of KingsX.

Early.Very early. But no matter, I am not sleeping at the moment anyway.
