Technology wise I think Broadwell would, should suffice my needs with plenty of miles. My only worry, fear, concern is what if with Skylake Apple completely redesigns, changes, the Body, Chasis of the rMBP making it extra more slim or change the screen display technology or something of that sort...now that would really hurt me more than not having Skylake !!
Do you think with Skylake the entire design (Chasis, weight, screen display) of the rMBP also might change ? Do you see that happening ?
IMHO the whole rMBP as a package ( purely talking from a body point of view) now stands at its most refined state, so I don't know what else can you change in the total body of rMBP ! But is the rMBP again in line for a big total overhaul in terms of body ? With Skylake ?
I don't expect any major design changes with either Broadwell or Skylake. The rMBP is still too new for that. Likewise, I don't expect any changes in screen resolution.
