We have been hearing that Apple is bringing a 4-inch iPhone for 2016. Dubbed the iPhone 5se, it is expected to come with a 4-inch display and the new 12MP camera from the iPhone 6s. Consider this the iPhone 6s mini of-sorts.
From what we hear, the unveil will happen at Apple's big spring event to be held on March 22nd.
Coming back to what we know, we are going to see the touch-ID return on the iPhone 5se but there won't be any 3D Touch here. Pricing is expected to be around in the $400 - $500 bracket with 16GB and 64GB storage options.
