Probably not, but I would like to see a new TB monitor. I actually replaced mine with a Dell 27" 4k. You can find them under $500, and I bought mine for something crazy like $350 I think (open box at MicroCenter)

My late 2013 rMBP is still great, but I do admit I'm eyeing an XPS 15 (or similarly spec'ed machine) and putting Ubuntu on it. For the price of a 15" MBP, twice the RAM, touch screen, 4K display, etc seems quite appealing.
