Ah, the beauty of the internet. Even though I explained my reasoning in depth, made lots of good points, my posts are simply dismissed as total garbage by Sagaris (without any explanation given as to why I haven't thought my position through), just because he doesn't happen to agree! Yep, you're the boss mate.
I believe there is a strong argument to be made for the deletion of the very old original tracks from the PS1 era.
It isn't as easy to redo them for PS3 as you may think, you don't just bung 'em in that easily. It still takes considerable dev time to remodel them for next gen. Why not do a new track instead that you'll grow to love even more? (real/fantasy/whatever!)
Its basically a give-take compromise regarding new/old content. If you have all the old tracks, you (by default) get less new stuff, maybe only a few new tracks, which wouldn't be very exciting to me.
Why the lack of enthusiasm for new content?
