It comes as no surprise that GTA V will have DLC, but it’s worth keeping in mind that it will be region-locked. According to the Rockstar support page, any downloadable content will be tied to the PSN store of the designated region.
This includes any extras found in the collector’s edition of GTA V. The whole situation is a bit convoluted, but here’s the example Rockstar provides.
For example, a North American PS3 GTAV disc (BLUS31156 code on spine of box), Japanese PS3 GTAV disc (BLJM61019 code on the spine of the box) or Asian PS3 disc (BLAS 50639 code on spine of box for Singapore, Hong Kong, Taiwan. BLKS20442 for Korea) will play on a European PlayStation®3 console. However, if you live in Europe (where the GTAV disc code is BLES01807) you will likely have a European PSN account that will not be able to redeem a US pre-order code, and will only be able to download Region 2 (European) DLC, incompatible with non-European discs
So if importing plays a part in your usual gaming routine, you might be better off sticking to your own region this time around. Grand Theft Auto V will launch worldwide for the PS3 and Xbox 360 September 17th.
