It seems that the next GTA game in line to get the mobile treatment is one of the expansion packs of GTA III. Could Liberty City Stories be coming to iOS and Android next?

All the GTA games from the so called 3D universe, namely GTA III, Vice City and San Andreas, have been ported to mobile devices for their 10th anniversaries, and also subsequently ported to both the last-gen and current-gen consoles since. Both III and Vice City later received standalone expansion packs with all new stories, missions and characters, albeit in the same settings. With the main games of the 3D universe having gotten their respective mobile ports, it is only logical to assume that the expansions are up next.
