Again - before it actually comes out i can only be guessing. We'll definitely know only when we hold it in our hands. Until then everything is possible, although not everything is really probable.
I think if you look at the first Shenmue conversion - Shenmue 2 for Xbox - it reveals a bit of how "they" do conversions. Basically only the sound driver was changed (Dreamcast AICA is not really compatible with xbox) and the songs recompiled. The rest is pretty much the same. Of course the ingame emulators (Hangon, outrun, etc) were also a bit modified, but basically "that's it". And as an xbox is fairly similar to a PC i would be surprised if they did it "much different" for a PC version.
Another theory to take into account is a real "Dreamcast emulator". Unlike nullDC it would of course have to run smoothly and without flaws. I think the games they already released work like that. I don't really know any technical details so i am mostly guessing, but i think most of them run a "better nullDC" and just load the original game or at least very close to that. Obviously in that case there would be virtually no changes at all to the game.
Widescreen would just be a flag in the engine to output a different screen res. However not all games would be great in widescreen. In Shenmue i think some cutscenes are so much optimized for 4:3 that parts of the edges of the scene would look "cut off", you could not see that in 4:3 but in widescreen you'd see like "Oh the room ends there". Not sure if Shenmue would look "perfect" just by enabling widescreen or if at least some cutscenes would need to be remade.
