1) Sony will have to bust their ass. They plan on making this generation last longer than any before it, and for good reason. Of course, they've planned the most for the long term so it will eventually take off either way.
2) Then Wii will win the war, at least in NA. I'm not sure anything can stop them from winning it in Japan, and I'm not sure they can win it in Europe or that they are doing all that well there as a whole.
3) Who cares? It'll have very little impact at all, unless it's a genuinely more powerful machine that they intend to transition into being the norm in a few years. Short of that, it's just another overly priced machine designed for the hardcore in mind.
4) The first will happen, the second probably won't. While they both exist in the same markets, they really don't compete with eachother and that means the success of one is not the failing of another. Sony seems to have said something to interest retailers in regards to that product line, so they will likly be capable of maintaining their handheld business even if they can't beat Nintendo.
5) It's gonna be massive. It will probably set sales records like mad, taking best first day sales among others, and will probably break 5 mil in Japan.
6) I don't think that's a "when" anymore. Previous to the PS3's launch HD-DVD has 66% marketshare. Since the launch, BR has taken up the same 2/3 majoity of sales. It's not stopping, either. As the PS3 sells more, BR sells more. As BR sells more, BR players (such as the PS3) become cheaper to make. As the PS3 becomes cheaper to make, Sony gains ground in the DVD market. Hopefully, somewhere in there they have a plan to improve the games factor since they are losing exclusives rather quickly.
