Will DVD be inheriting HD DVD's web features?

[AndimerForts]

As the primary backer of HD DVD, Toshiba spent a lot of money developing technology that they didn't get a lot of use out of. Some features from HD DVD players, like upscaling, fit nicely into standard DVD players. Others, like web-enabled content, aren't quite as applicable. Sure you could put the same capabilities into a DVD player, but with no official standard you'd be hard pressed to get anyone to take advantage of it.

I don't see anyone expanding the capabilities of standard DVD players or media.  It's more likely that they'll incorporate those features into BluRay.

Those feature are already incorporated into the latest Bluray standard, although the PS3 is the only capable player for that updated standard at this point, unless the newest devices can already perform.
