like up to 3 major updates at least. This phone has the specs that will make it a top phone for well over a year. I mean the newest phones are still coming out with just 2gb of ram (maybe the S5 will have 3gb) and the CPU at 2.3mhz will be a beast for a long time. Then look at the S3 now confirmed getting 4.4 KK so it's easy to see 3 major updates for this phone and maybe more.
