Unless the developer puts a similar amount of time/money/manpower that went into GTA V, I doubt it will be as good.

For comparison purposes, GTA IV had the highest budget of any video game every created of $100 million dollars, with Gran Turismo 5 being next in line at $80 million. Then you have the insane development time with huge development teams spread across different studios all across the world...
