I followed the launch of the new MacBook Pros very closely and like many pro users was disappointed in the apparent design priorities for the new generation. (although it is a beautiful object, in and of itself)
While smaller and lighter is nice (in a vacuum), better GPU options, higher RAM limits and longer battery life are way more important to pro users. And don't get me started on dongles
It remains to be seen how useful the touchbar is — or will become, (depending on the degree of developer support) — so I'm not as down on it yet as Dave. But in and of itself, it's not compelling enough for me to upgrade, especially in light of the other deficiencies.
The other major issue is the significant price increase — of an already expensive line. In Canada, the combination of price hike and currency exchange means that an upgrade to an equivalent model is almost $1000 more... crazy!
My current MacBook Pro is only 2 years old, and it's not groaning yet. So, like Mike, I will wait for gen 2 and see if the price comes down and better GPU options (i.e. nVidia) / higher RAM limits are introduced. We'll see then.
