need opinion on upconvert dvd vs. high definition

[Delusional]

i rarely buy dvds anyways. most of my fav movies are from universal and warner. i don't see why hd dvd and bluray can't coexist. just seeing how there are companies producing both version, seems like manufacturing costs are low to do a slight process change. there's always just the dvd version and do upconvert if needed, but i'd go for the cheaper version for now.
