For anyone that doesn't get a boner over graphical fidelity, this is probably the most pointless Remake ever announced.
From a gameplay, plot, writing, direction perspective, (Edit: Visually as well), there's nothing about the original MGS 3 that needs to be Remade.
If you want the ultimate version of MGS 3, play MGS 3... Through Emulation or officially (Don't know where it is available).
Unless you go the Final Fantasy 7 Remake direction, which I very much doubt they will do...
Anyway, sorry. I just really don't see the point. Silent Hill 2 too, funnily enough. Konami has a talent for wanting to Remake games that don't need one.
It looks shiny, that's all I can say...
