Apple's iPhone 5 and Samsung's Galaxy S3 should debut this year with the latter possibly slated to debut at February's Mobile World Congress in Spain. Samsung debuted the Galaxy S2 last year at the event, so it could do the same this year. Apple, however, has not indicated when the iPhone 5 will arrive. iPhone 4S debuted in October, but it came out over a year after iPhone 4, so Apple could repeat that cycle, and that would put iPhone 5 nearly into 2013. Whatever Apple decides, legions of customers will line up to buy the newest device, but they will be endlessly comparing it to the Galaxy S3.
