Re: Wow so he knew about all the chip roadmaps.....
1. Chip roadmaps can extend decades into the future. Once you get past a few years, they become less reliable, but...
2. As mentioned in the article, designs do begin several years before the products are actually built. At the beginning they might no't get into specific details, but are based on the current roadmaps' estimates of functionality. As the release date gets closer, features, functionality, and even the product/release date are adjusted to account for what actually has happened in the supply market.
A perfect example of (2) is the iPhone 4S. Everyone was expecting the iPhone 5 with Siri, and Apple comes out with an updated 4 with Siri in beta only. Why? Because the anticipated battery life, CPU speed, economics of the larger screen, and development of Siri all came in behind schedule.
Apple, Samsung, et al. live and die by keeping up with the bleeding edge of technology -- but design, prototyping, and testing can take years. So they have to design based on future specs, prototype with often half-baked silicon, and test on emulators to get the product out the door while it's still relevant.
So, yes, SJ knew about the chip roadmaps as of 2010, and was actively involved in the first stages of design and development of products extending at least 5 years out. In the archives of any decent tech company there are designs for devices and feature sets we don't even know about simply because the roadmaps were off and the capabilities were either not there or were superseded by something even better.
