I currently have a mid-2014 rMBP (15"), and I am planning on upgrading to the 2nd gen of the new 15"MBP when it comes out later this year or next. However, I need to purchase a monitor now. I am really confused reading about ports/adapters/etc. If I go with the 5K LG endorsed by Apple, will my 2014 machine be able to drive it? I've also considered getting the discontinued Apple Thunderbolt display, but will it work with the new MBP? Or is there any other screen you'd recommend? I like the 27" size. One thing I like about the Thunderbolt display are the built in ports for ethernet, etc, but then again, will those work if connected to the new MBP?
