Well it's mainly because they can sell it. If the N64 and Gamecube were hits, I say they would have had revisions as well.

true, I'm going to get one regardless. It just sucks because they do this on purpose.

But it wasn't for the purpose of milking. First of all, if the gyroscopes had been as small as they needed in 2005, or even 2006, they would have been included in the controller at launch. But the earliest ones reportedly were available in 2008 or 2009, which is when the Motion Plus launched.

Anyway, at that time, they could have included it in the Wiimote itself, but that would have been forcing customers to pay even more money for not only the extra motion control, but for a controller they already have. That was why the Motion Plus was optional, so that you would only have to buy the dongle.

This is not meant for people to buy all new controllers if they already have a Wiimote and Motiuon Plus. This is for people that want to get another one, or who haven't already.

AHEM!

Actually they were already small enough, and cheap too, in 2004:

In wario ware twisted I belive the sensors can't replicate 1:1 and have 3D dimensional space recognition?

That's just a tilt sensor....

The gyro that game used is this one:

Nec states it's sensitive to a very wide range of angular speed and its 3D version, using 3 gyros, was already very compact, just 6cm³ volume compared to the 30cm³ of the previous tech viable for mass production.

Obviously current tech must be even cheaper and smaller, but that one was already viable for a hand controller, and precise enough, as it was used also for camera stabilization.

how is this any different than Sony or Microsoft?

still getting two WM for my two regular wiimotes some time in the future, one with WSR and one separately (or maybe in another bundle). But this is cool, I want it too.

According to Nintendo they weren't small enough and cheap enough. They also had higher demands than the typical sensors in Cameras (and probably that game). They needed theirs to measure rotations 4 times faster than a typical camera gyro.

Sure, you could get a small one that met their specs, but you have to remember that Nintendo wasn't planning on selling the fastest selling console ever. They were planning on making a console that would sell and be cheap enough that they would survive even if they only managed GC level of sales.

just a quick Q regarding wiimotion

currys digital have red steel 2 on sale for only £2.95 get them while you can.

will red steel 2 work with a normal wiimote?
