While I can understand some people feel shortchanged about paying additional money to get functionality they feel was promised originally, I'm still pleased that we're getting MotionPlus at all considering Wii is such a runaway success without it. Not that this is an act of charity from Nintendo by any means (I'm sure they will make plenty of money out of it in the end), but it is a somewhat risky move in the way it will segment the market, so I'm happy we'll get this experience now rather than having to wait until the next console or whatever. Having to pay for it to this extent is not so pleasurable, but ultimately I'm willing to do so because I'm confident it'll be worth it.
Also congratulations to GoldenPhoenix, her most recent post in this thread is her 10,000th here on the forums!
