These things are always personal... for my use case, I do need a quad core CPU and portability, but these CPUs seem like they're the best compromise for speed and TDP that Intel currently offer, so I don't see what else Apple could do there. I also really value the larger track pad, the better screen, and the reduction in weight. So for me it would be a nice upgrade. I can completely see how it wouldn't be suitable for someone else though.
Ok, now from my point of view: slower CPU (I don't edit video, I don't need 4 cores), new keyboard layout (I don't have any issues with current trackpad), same screen (100% brightness level? never), no USB-A port, no HDMI port (and I hate adapters hell). And 15" version is not even an option because it doesn't have Esc button and F-buttons - I use them every 5 minutes in IDE.

As for the Esc-button, they've added an option to macOS Sierra where you can map the modifier keys to Escape. Very useful to have Caps Lock mapped to Escape.
