How much longer will CDs be made?

I happen to have hundreds classical & jazz CDs-and still buying the wonderful, economical box sets now available; but, the concern is "will I or anyone else with a decent playback system listen to them when the "Hi Res" reproduction becomes available?".
I have been OK with DVDs and line doublers--but having just looked at a High Def sports game in a Sony showroom on a superior large Sony flat panel TV I see a "very" significant" improvement.
I'm sure if I had that screen at home versus the previous technology there would be no question what I would use.
If there is a similar (mindbogling to me) improvement in stereo sound I'm just not sure I would ever listen to my old discs? What do you think considering our present CD sound versus a Blu Ray type improvement?

Cadnliz,
I notice you use a Lexicon RT-10.
How has it been for you?

Sidssp,
You comment about a good DAC sounds sensible to me.
Perhaps it can be driven by my old Toshiba SD9200 in which case the Sony can be sold to contribute to the DAC.
What do I need to spend on a DAC to surpass the CD sound from the Sony?

Tiger, you have a very good point-but!
Sony could actually enhance Blu-Ray sales(ok, not by much) by making it a state of the art Hi Res 2 channel audio player as well as the video star it is. The additional cost would be minimal and it would make the player the greatest all-rounder in the world-surpassing SACD quality for example.
Sony entertainment could benefit hugely by making all artist production at a significantly higher level.
Sony could also revolutionize the recording studios and Blu-Ray CD music and video industries with their new higher quality format.
Come to think of it- this idea is a no brainer--but--will Sony do something this eminently sensible?
Anyone from SONY listening in?
(I also think that while people are excited abouy the enhanced movie enjoyment from Blu Ray this is the ideal time to add further excitement with truly HI RES AUDIO.)

Tvad, Thanks for the update.
I did not know that Blu Ray players actually played a Hi-Res format for AUDIO.
If you are right-that the Blu Ray provides Hi Res audio-like full 24/96 or 24/192- it puts a whole new angle on things for me.
I will check into it further but I don't remember any posts here on Audiogon raving about Blu-Ray sound.
