I can't agree with you CaptainSnow. The 800 cc. machines will be faster than the 990 cc. sooner than later and so much so in the corners. Richo here said that they will not be lighter either. In other words, they will not be more secure. Security is more related to the design of the circuits, even more than the traction control, for instance.
Technical reason:
The problem is that 990 cc have their power delivery capped to 80% everywhere except in a few straights, all circuits combined. Even that is not enough to prevent tyres degrading quickly because the relatively slow curve speed has to be compensated with sheer acceleration and braking. This means that tyres technology not only didn't catch up with the electronics, it also became absurdly expensive.
Political reason:
Honda is the incumbent and are happy to throw in huge resources to take advantage of changes in technology or regulations. In fact, they imposed this, and the rest have to follow.
