I'm torn on this one.
If they don't release systems with > 16GB of RAM, I may pass on the new model and see what the refresh brings us.
With the relatively low rumor leakage with in depth info outside of the goofy OLED touch bar, I'm not entirely certain what to expect yet other than USB-C and Skylake. It's remotely possible they release 12" and 14" models with closer-to-borderless displays, and I'd love to see a quad-core 13"....but don't think it's in the cards, especially with the lighter and thinner mantra.
Assuming no format/size change and no quad-core in a 13", I'm in for a 15" MBP with dGPU to replace my aging-but-still-graceful (except battery life) 2011MBP/16GB RAM/1TB SSD...both larger SSD and more RAM would be of value to me and may determine if I pull the trigger on this release...or wait to the next.
If I wait, it may become tempting to pick up a NOS or used 2014/2015MBP...
Anything > $2K for a laptop is already fairly insane when the 'pro' in the name doesn't quite live up to the specs, but am expecting 'the usual' ~$2500 + likely upcharge if they offer a 32GB RAM option.
