All the new updates on the second generation model will be the 144 Hz/7 ms and 4K UHD Pantone-certified display options, USB 3.1 Type-A instead of USB 3.0, a faster UHS-II SD reader for up to 300 MB/s, a slightly thinner 1.8 cm profile, Dolby Atmos audio software, ambient light sensor, a sleeker "AERO" logo, and finally a hexa-core Core i7-8750H to top it all off.

This thing is looking pretty freaking sweet (and I'm loving the new logo), BUT I don't think I can justify the purchase until they update it with the TBA 1100/ 2000 series Graphics cards. I'd also like a glossy screen option for the 4k model, but I suppose beggars can't be choosers lol.
