HD now Irrelevant?

[-3db]

Since Avid now will no longer develop LE and M-box

"Pro Tools 9.0 provides a single, unified installer for Pro Tools and Pro Tools HD. Pro Tools LE and Pro Tools M-Powered software will no longer be developed. Pro Tools 9.0 effectively replaces all lower versions of Pro Tools LE and Pro Tools M-Powered software.
You can upgrade from lower versions of Pro Tools LE and Pro Tools M-Powered to Pro Tools 9.0 for use with your Pro Tools LE or M-Audio hardware."

Current HD hardware is now legacy, isn't the future state just varying levels of HD? Complete Production Tool kit 2 = HD? I don't know this is confusing...

So what is the point of an HD designation?
