OKAY the new gta is coming out in two or three months, Alright listento this but this is a major spoiler. at the end of gta four there is a check for niko it says VICE CITY on it and there is alot of monuments of vice city in gta four at the mini golf course. and in the ballad of gay tony one of the radio stations is VICE CITY so most likely new gta is in modern day vice city.but maybe not at the end of gta the ballad of gay tony during the credits you can see pakie leaving with a bag to the airport now in gta 4 he lost everything so most likely he is going back to ireland maybe you play as him. and in tbogt thers a sign in star junction saying LIBERTY CITY IS OVER NEXT STOP SEAGULL THEATRE which is a real threatre in EUROPE and some of the shops there is fake brands from san adreas anda poster soooo manyplaces gta can be on good idea could be TOKYO. i will be back with more info
