Will Apple release a new iPhone in 2015?

The 6S, yeah

Judging from 2007, 2008, 2009, 2010, 2011, 2012, 2013 & 2014 I would say there is a good chance of them releasing a phone in 2015.

It would look like the iPhone 6.

Either that or a new OS update. Or they will be stupid and make a 6"S". It sounds so stupid lol

They seem to release new ones every year lately, so I wouldn't be surprised.

It'd look a lot like the iPhone 6. The design only changes every couple of years.

If pigs fly
