I'm wondering what happened to the planned "possible joint development of future nodes with TSMC" that was rumored/teased a few weeks ago, where Intel seemed like they would partner with TSMC to split the cost of next-gen Node R&D in exchange for Intel possibly opening their fabs for 3rd party designs. The article confirms that Intel is partnering with IBM thus far, and is willing to fab possible rival chip components. Heck, hell may even freeze over and Intel could also be fabbing their rival's (AMD's) chips, since some of the earnings will still go back to them as part of the manufacturing deal. Of course, that assumes Intel improves Nodes to really match TSMC and doesn't steal IP design elements.
As well, I wonder if their Arizona Fab expansion will be a possible joint operation with TSMC, or if it will directly compete against TSMC. If it's the latter, TSMC is going to have trouble headhunting talent against Intel (something Ian Cutress mentioned in his Anandtech article on the TSMC Arizona deal).
