Iphone 5 or wait for iphone 5s?

I'm on verizon and my contract is ending in april and i want the iphone 5, i currently have the iphone 4, i got the i4 in sept of 2012.i've heard rumours about the iphone 5s that its releasing around summer. Should i upgrade to iphone 5 or just wait?

Added (1). And i'm upgrading from my upgrade date to august…

Better to wait

Get the 5. The 5S will be an incremental upgrade from the 5.

Get iphone 5-will e cheaper than iphone 5s and when you upgrade the iphone 6 will be out!<3

I'll say wait for it but just don't expect too much from apple right now because they are way down in business with other phones but although wait until it releases it can be way better than the iPhone 5

Well nothing concrete has said they would be coming out in June/July. So as of now September is the expected release time.
Either way, it seems close enough for you that I would wait for the iPhone 5S. If April then you'd have to wait 5 months though.
