I had a feeling this would happen. Sony have seriously messed up, it was reasonably obvious that they wouldn't be able to get the launch to the scale that they wanted with them employing at least two new and troublesome pieces of technology in its system (Blu-Ray and the Cell processor). It's been building up to this for weeks now, and it would have to be Europe that would be the territory of the three that is the fall guy.
I presume that they've chosen to roll out in America mainly because of Microsoft's rising power with 360. They know that they can't afford to let Microsoft get much more ground and have allocated the biggest amount over there. One problem, Sony - Europe is also getting very happy with 360. The damage they will sustain a little in USA will still continue in Europe for a whole extra five months. The lack of units being given to Japan just prove how arrogant they are, thinking that they have no competition over there due to 360 being a flop. Evidently they think that because Nintendo can beat them at the handheld game, they can't possibly win two battles at once.
Bad news. Wii is, like 360, gaining power, only at the moment it's only in terms of hype. The hype is getting massive though, like a rock picking up momentum as it's going down a hill. Look at Nintendo's share prices, they're going up and up at the moment. It's not just the fact that DS is doing stupidly well, it's because the excitement for the Wii launch is rising. You only have to look at the way Nintendo is being treated in shops in the UK, a place not traditionally known for liking Nintendo in the last decade, to see that they're onto something special at the moment; their stuff is being placed at the front to attract everybody's attention, while Sony is being relegated to further back in the shop. If you want more proof of the rise of Wii, look at messageboards like NeoGAF
