Buying a 16GB Nexus 4 now or wait for the 5?

Hi guys, i have a question regarding to buy a nexus 4 NOW or should i wait until the 5 will come out in like October or November?

My only concern with all this is that my budget is pretty tight lately since i only go to college and dont have a job.

Do you think the cheapest 5 will cost 299 like the 8GB 4 did when it came out?
