Should i get the new xperia z2 coming out or wait for a new iphone?

I have an iphone 5 right now and i'm thinking of getting the new xperia Z2 soon which one would be better the new iphone series coming out or the xperia z2?

I'd suggest you wait a few more months, maybe till March end. That's when almost all important phones get realized. If last year's schedule is anything to go by, the Z2, Htc One (two), Galaxy s5 should all be making an appearance. Apart from a nexus or an ios device, you should have pretty much all your best bets in the market by then,

Personally, I'm too looking for a new phone, and I'm considering everything from the Z2, htc One 2, S5 with cyanogen mod, Lumia 1520 and maybe even the 928 because the rumors say that we can expect it soon.
