Best Buy iPhone 4 to iPhone 5 trade, is it worth it?

Okay so best buy is doing their trade in where I give them my iPhone 4 and if its in good condition I get $150 for it and I can use that for a iPhone 5. Now my question is, with the WWDC conference going on and them announcing iOS 7 and possibly iPhone 5s/6 is it worth it to get the iPhone 5 or should I wait until they release the next iPhone? I know they haven't announced any new phone yet but we all know its coming out within the next couple months… I guess I'm just asking if its worth it to wait or to just get the iPhone 5… Please help.

I think its worth the wait. Ios7 is it completely different and the iphone 4 is getting a little old now

I suggest you to wait for iPhone 5s, as apple has launched iOS7 with cool features like a radically overhauled interface, new Control Center, transparent animations and more.
