Will doom1 and 2 be optimized to use on newer systems?

From what I've heard, the 360 versions will be based on the XBLA ports, while the PS3 versions will basically use the same engine as Rage, just with the Doom games running on top of it instead of Rage itself. No idea how the PC version will be handled.

All of them will be the same and all of them will have XBLA versions' netcode and id Tech 5 engine.

I hope your right Richard. Then again, I don't mind substituting the port with engines built by the Doom community.
I'm curious as to how XBLA ports perform in regards to most common ports downloaded from the internet.
(I'm apologise, I haven't owned a xbox360 or a ps3. Things are expensive enough with a PC and game consoles nobody seems to talk about anymore.)

the topic was classic doom. doom3 hd remake is using engine code from doom3- and rage-engines. of course not the classic versions.
