It's an impressive showcase. Nevertheless, some may feel that this is what the Wii remote should have been capable of in the first instance, rather than having to purchase an additional peripheral. Miyamoto, however, explains how this just wasn't possible even a few short years ago.
"It's a continuous evolution. Not all the Wii software requires Motion Plus, so it is appropriate for us to position it as a peripheral," he says. "Also, it was not technically feasible for the technology to be realised with such a compact size. The fact we are now being able to sell Motion Plus at this price, at this size, is the result of technological advancements in the field of microelectro-mechanical systems, which took place after Wii launched."
