Should I get the Sony Xperia z2 or wait for the z3?

Ok I have an iphone 5 right now and before I had the nexus 4 but I sold it due to screen problems(dead pixels) so dad gave me his iphone 5 after getting the 5s. IPhones are cool in ways but I think I prefer android phones overall (the good android phones) I like nexus so I was thinking between the nexus 5 and z2 and I've kinda decided in getting the z2 the nexus 5 is great and it's a nexus but the z2 just offers more for me. Anyways mum said she might get me a phone after we come back from holidays (August) and when I sell my phone. So possibly August. So sony releases phones every 6 months and the z2 was released in April I think which means the z3 will be released in October. Ok so the good things about getting the z2 is that it's going to be cheaper and I'm getting it before the z3. But the z3 is probably going to be better but more expensive and I'm gonna have to wait longer. Mum also said it depends on the budget so I'm taking the price into consideration. So what do you think?

I personally don't like the 6months release that sony is doing. I'm having a hard time choosing between the z2 and z3. I have had z and z1, i want the z2 but i'm hearing about the z3 with a few leaks. Leaks says its gonna be a new design. When the z3 release is expected cost about $800+ for a few months. Maybe about December before the cost goes down to about $500 - $600. Z2 is currently available for around $600 on eBay. Within the next month the price should go down to about $500. Z2 is a very good phone most of the faults i found on the z and z1 were fix including screen quality, camera and battery life.
i recommend you wait another 8weeks for leaks and see if the new design of the Z3 is nicer than the Z2 then you make your choice. I don't expect specs to change by much, by then the z2 will be able to fit your budget for a high end smartphone. If the z3 design makes you want to wait until December to January for a nice price of around $500 -$600 on the z3
