Expansion of Grand Theft Auto series locations

[Ultra Fit Trio]

Hello everyone.I'm new to the forum.Been playing GTA V for the past week and I enjoyed it pretty much.However,one thing I've noticed is that most of GTA games are set up in a fictional way based on cities like New York and Los Angeles,Las Vegas and San Francisco.I wonder whether Rockstar Group in general have sparks whether there will be GTA games in the near future based on cities like Tokyo,Shanghai,Hong Kong,London,Paris,Rome,Berlin and so on?

Hopefully my question is not too much to ask for.

Thanks.
