So HTC have just announced the HTC One Mini which is basically a miniature version of the HTC One with less features. IMO it looks quite nice as a mid-range handset.
There isn't any word on the pricing, although it is supposed to be cheaper than the HTC One (obviously)
How it differs:
-4.3" 720p screen instead of 4.7" 1080p
-Snapdragon 400 1.4GHz vs Snapdragon 600 1.6GHz
-1GB RAM vs 2GB RAM
-1800mAh battery vs 2300mAh
-16GB storage (non-expandable)
-No IR Blaster
-No NFC
-No Optical Image Stabilisation (OIS) on the 4 Ultrapixel camera
What hasn't changed:
-Android 4.2.2 with the same Sense UI
-Boomsound - dual front facing speakers
-Same aluminium design
-still has LTE
