Like Archangel and Spockrock already said, I don't care about seeing a one to one remake of X-Com. I dislike remakes in general because they are inevitably pointless or in some cases even damaging to the original (see Silent Hill remakes), but more so in the case of a 2D, sprite based game like X-Com. The X-Com style is simple, stylized, easy to identify, timeless, as such making it more realistic and 3D based would cause it to look worse, if anything. Not to mention the feasibility of such a 1:1 remake. Bringing something from 2D to 3D would already require reinterpretation of the sprites, at which point people would complain that it is not being faithful to the original. (For an example of this look at the different manner in which the sprite based monsters of Doom were reinterpreted for both Doom 3 and nuDoom; both games were remaking elements of the original, and ended up with wildly different results, both of which get their own shares of criticism). Then there are issues like how would they possibly handle the large scale, totally destructible environments of the original while simultaneously having modern, high fidelity graphics; or how would they handle the large amount of troops you could bring along in the original. Trying to be a 1:1 remake would end up being nitpicked apart for all the concessions they would have to make, so why not spend that time making some new.
tl;dr the original X-Com will always exist and if I want to play the original X-Com I will install it and launch it. Having Gollop lead a superficial remake would be a waste of his talents.
As it is, the UI was the one part of X-Com that I never cared for, a mess of icons that I got sick of clicking over and over (even though from a visual style point of view there are messy, overbearing UIs that I do like, such as in SS1). Just because X-Com is a masterpiece, and was the first to do a lot of things in the genre, doesn't mean there are elements that are above being experimented with or, possibly, improved upon.
