October/November and still ships with Skylake...
Get with the program Tim!
If the rMBP is updated in4th Quarter this year is there actually any point in going with Skylake? Isn't Kaby Lake released by then (obviously assuming no Intel delays)?
No - the Skylake chips appropriate for the MBP literally just started shipping. If Kaby Lake is on a similar schedule, those won't be out til around this time next year. There are many variants of these chipsets and they don't all come out at the same time.
