'Will' is a bit absolute for Intel's current situation, 'planned to be' is probably the better phrasing. I mean, by that timeline Ice Lake should already be in machines on the market en masse (it states halfway through Q2, we're now into Q3). Also worth pointing out, what Intel is now releasing as '10nm' isn't anything like what they were promising in 2014/15. I've read 18-20% improvement (single core), which isn't to be sniffed at, but that's over Skylake! Intel have basically said their first steps into '10nm' class chips will be more like transferring their 14nm designs onto a 12nm manufacturing process, with none of the ambitious density increase that made previous shrinks significant. It sounds more like this will be similar to Kaby Lake over Skylake - it will run cooler and that will let them up clock speeds a little bit. I'd really love to be pleasantly surprised, but I'd definitely advise keeping hopes somewhat restrained.
Yeah I've read the same, however I'm more excited about a potential redesign. The fact that the 13" MBP now packs a quad-core processor is more than enough juice for me, plus the graphical improvements are quite a bit better compared to the CPU improvements, so that's a plus.
