No, the second generation XA-2 Toshiba will have 1080P output, and all HD-DVD disks to date are 1080P on the disk.
Also the Xbox 360 with the add-on HD-DVD drive can do 1080p using a VGA cable (only up to 1080i using component).

1080p is an ATSC spec just the 24fps variant.
I believe the 1080p/30fps is also.

The problem then becomes the bandwidth requirements to transfer so much data:

* 720p60: 1280×720 gives 0.92 megapixels per frame. If we take a 24-bit color value per pixel (RGB), this means 2.76 MB data per frame, which multiplied with the 60fps gives 1.3 Gbps or 165 MB/s.

* 1080i60: 1920×1080 means a 2 megapixel frame which translates into 6.2MB per frame. The interlacing cuts the bitrate in half: 6.2MB x 60 / 2 = 1.49 Gbps or 186 MB/s.

* 1080p60 is obviously double the throughput of 1080i: 2.98 Gbps or 373 MB/s

Straight from the horse's mouth:
I sit corrected. It is actually my particular TV that won't accept a 1080p signal over component, only HDMI and DVI. Many TVs will have this issue.

Nice! From my research, Samsung and Mitsubishi make the best quality DLP TVs.
