There won't be an Xbox 1.5, says Phil Spencer

Not as much offended, more concerned. The biggest advantage of consoles is 1 hardware spec.
Half gen upgrades means lower profit margins, more work / longer game development and no more fully optimized versions. Look at the difference between QB and Uncharted 4, one made with UWP in mind, the other custom tailored to the console.

I'm all for a premium SKU, if that means a large SSD/HDD hybrid, 4K UHD player, dedicated VR port, 5ghz wifi, and/or hardware BC. Just leave the hardware spec for games alone. Nothing good will come of it.
