Are affordable mainframes the future of virtualization?

Companies that build mainframe computers, especially in the Intel-based architecture lines, have decided that these mainframes can compete with traditional virtual and cloud infrastructures for market share. The new so-called affordable mainframes are fast, far less cryptic, and easier to maintain than your father's (or grandfather's) mainframe computers were. Mainframeologists will tell you that cloud computing is really mainframe grid computing and that virtualization is really a mainframe technology ported to Intel architecture. I'll buy those assertions, but at a slightly discounted rate. I discount them because virtualization and cloud really weren't so user accessible back then. It might have existed, but only a few people had access and interest. I'm taking off a healthy 25 percent for that.
