The current design is pretty old considering it debuted in 2012. The previous redesign to unibody aluminum was in 2008. So come 2016 when Skylake is readily available, it'll be 4 years. A redesign is imminent. Before anyone says how come we need one, well look at the MacBook. The motherboard was reduced to 1/3 the size of the MacBook Air. If major advances in CPU and GPU technology can happen, so can motherboards and all the other parts in a laptop. Will you skip Skylake if a redesign doesn't come with it? I've waited this long for a redesign, I can wait one more year.
