- 64-bit A8 processor
- 32GB or 64GB of storage
- 2GB of RAM
- 10/100Mbps Ethernet
- WiFi 802.11a/b/g/n/ac
- 1080p resolution
- HDMI (1.4)
- New Siri Remote / Apple TV Remote
So the HDMI spec will be 1.4 (not 2.0) which means no vastly improved audio which could have aloud for features such as Dolby Atmos. 1.4 can support 4k video but that brings me to my next point. The marketing so far states 1080p and and they used their A8 processor instead of the A9 so it's technically a generation behind from the offset.
One thing that people have also noticed is the lack of optical out this time around. Some customers who were using this (particularly with Amp setups) will not be pleased there.
My last point is on gaming, I haven't seen a reference design for a controller or set layout for buttons which would add consistency for game devs. I think they are going to struggle to make real gains here without that.
