I was just wondering will there be a fallout 4 coming out?

It's more than plausible. Though Fallout 4 discussion, for location and just general theories/suggestions go in these respective threads: http://www.gamesas.com/index.php?/topic/1255186-official-future-fallout-locations-suggestions-topic-9/ and http://www.gamesas.com/index.php?/topic/1278543-fallout-4-speculation-suggestions-and-ideas-43/

You'll find plenty of people discussing it.

Ok thanks for telling me i will check it out
