Nintendo: I'd say the biggest weakness for Nintendo is its lack of third party. While they probably won't need any more third party support for the rest of the Wiis run, I feel it should still push to gain as much third party support it can get before the next consoles launch. Because its the next console where Nintendo will need the most help and if they obtained more third party support, that's where they could really soak up the rest of the console market from its competition.
Sony: Sony may be in 'last place', but I think they've set themselves up in a good position for next generation. However, they still have a monster habit of trying, desperately, to copy every little thing their competition does in a mad grab to follow fads. From trying to jump into the motion control market (three times) to trying to patent multiple new Nintendo inspired controllers (what else is new) to even trying to one up XBOX Live service, it always seems like they're one step behind their competition. Sony use to be the big technology innovator back in the 80s and 90s...but now its more like they're the copy-cats. What they need to do is come out with their own identity. Their own 'killer app'. Basically, do what Nintendo did with the Wii....but not just copy with Wii. And no, 'bigger and more expensive' isn't going to work.
Microsoft: Oh Microsoft...the little engine that could....with millions and millions of dollars being burned. They proved that they could turn a profit finally with a console...but now what? They're still sitting with a virtual deadlock market in America, lost steam in Europe and Japan still hates their guts. Still, its hard to pinpoint what their biggest 'weakness' is. If you asked me 2 years ago, I'd say it was because they focused too much on one market. The American/Hardcore market. But now...things have changed. From their advertising to their game focus, things have greatly changed. Microsoft has gone soft. And I don't mean, they no longer are 'hardcore', I just mean, they are targeting the 'casual' market, like everyone else. But there's a price. When you start putting time and effort into marketing to one group of people, another group loses focus.
So at this time, I'd say Microsofts biggest weakness isn't really a weakness, but a problem. They have a dual personality they are trying to keep in balance. They are trying to figure out how to focus on multiple markets, where before they only had to deal with marketing to one group of people. And of course...the whole issue of still not gaining many new console sales outside their target demographic.
