Do you mean the specification theorectically allows for higher audio and video resolutions, greater color depth, more audio channels, more info in general?

Blu Ray discs hold 50 GB vs. 30 GB for HD. Blu Ray bandwith is 48Mbit/sec vs. 30 Mbit/sec for HD. Blu Ray discs also have a protective hard coating.

You are correct in that Blu Ray players have gone through the three versions of Blu Ray 1, 1.1 and now 2.0. 2.0 is the last spec for full use of all of the potential in the Blu Ray discs. From now on most Blu Ray players will be full 2.0 specs and will be able to perform all Blu Ray functions.

Can I play Blu-ray on my HD-DVD player. ... with a software update?

HD-DVD’s and Directv HD programming look great on my 120 inch Screen from my Front Projection 1080 Projector.

You seem to know what you’re talking about. So spec 2.0 compliance, in player and disc, will do you for a while?

You know there will be spec mods. But will backwards compatibility be maintained? People don’t like getting burned.
