Fellow Mac gamblers, please estimate whether the next-gen rMBP will be released before Christmas (in 2015) or after (2016). Context: I am in truly desperate need of a new machine (my 2008 MB) is dying, yet if the Skylake-based series is only 4-5 months out, perhaps (perhaps!) I might be able to postpone the purchase and live on a cheap Mac mini meanwhile. I buy a new machine only every 5 years on average, and the Iris 6100 graphics in the current rMBP do not inspire perfect confidence.
