The only thing I have to wonder is why. Both Fallout and Fallout 2 look, run and play excellently on modern operating systems, and both are largely identical, engine-wise from an end-user standpoint. If you add Tactics into that equation, well, it does support higher resolutions out of the box, but its game engine is totally different and built for an entirely separate style of game. Exactly what benefit would such a port bring? There are already plenty of mods for Fallout and Fallout 2 to improve its visuals. While the original Baldur's Gate has some major technical issues on newer systems, crashes, save corruption, and other major problems which can be fixed by using the newer Baldur's Gate II engine, I just don't see Fallout and Fallout 2 benefiting in any way from such a procedure. At best, it'd be a "because we can" sort of project.
