What does it mean when a guy says "we'll chat soon"?

I have been talking to this guy for a while now and he has been acting strange for the past 2 days. He doesn't answer me as much. Today I spoke to him and he said he was going out with his friends and he said "we'll chat soon" what does that mean? He usually says later. Is it just semantics?
