Yeah, but shouldn't a split off still be considered an advancement? It's not really sideways progress as much as forked progress. Aren't steps towards a buttonless interface still advancement? Their execution might not be this gigantic leap, but the progress towards the eventual goal is still there.
Take NASA for example. The goal was to land on the moon. Does that mean the manned orbital flights weren't advancement because they weren't moon landings?
And Strid, I was getting at that what you consider advancement contradicts what you also don't consider advancement.
If you feel that the Wii mote moves closer to the buttonless interface than previous control schemes, sure. As a concept, it moves in that direction, absolutely. As technology, I'm not positive where that goes. Can motion sensing technology bring us towards a true virtual reality experience? Maybe there will be a primitive VR system that has some sort of gloves you use, and those gloves will be in reality an advanced relative of the wii mote. But I am not sure this will be the case.
I'm thinking the idea will be to trick your brain into thinking it's sending signals to your muscles but instead send signals to this input device. Though maybe this is much further off than the technology that can create the simulated environment... because of the danger of intercepting brain signals and the possibility this machine could malfunction and stop the signal from your brain to your heart to keep beating. It wouldn't take this happening many times for that to create a panic. I'd imagine if that happened to one in a million people there would be a shitstorm, even if it was statistically safer than driving to the store to get it, due to the weirdness of the way it could kill you.
