Erm... dude, the only other thing the KH team is working on is Versus XIII. That's it. They can certainly handle 2 games (especially since it's presumed to be on the Wii, and the Wii is EXTREMELY easy to develop for).
And what do you mean her credibility got ripped to shreds?
...did you even read some of those rumors she posted? >_>
Uh, the Wii is currently doing very well. Better than the PS3 as a matter of fact. If things stay this way, they wouldn't lose money at all. And by that I mean if the Wii continues to do well. Obviously the PS3 will likely be in a favorable position by the time KH3 is ready to be made.
There are more people owning Wii's than PS3's.
Well, yeah, there's more Wiis being sold than PS3s. But, the third-party attach rate for Wiis is awful - basically, Nintendo is making out like a bandit for their first party sales (the top 8 games sold are all Nintendo's own releases), along with their console sales, while third party games - even the ones with good scores - aren't doing nearly as well.
Also, in regards to the demographics, sure, the Wii might trend younger than the PS3 (due in large part to the PS3's price being restrictive to kids, no doubt). But, it also tends to trend highly casual - just look at what its top titles are - and KHIII just wouldn't fit that set very well. It's a numbered sequel to a game on a different line of hardware (which, I imagine, would be a turnoff to a casual, who would want to just jump right in - numbers imply a need to have prerequisite knowledge), and a 20+ hour action RPG to boot. It's just not the kind of thing that the Wii Sports set would go after, I don't think.
There probably isn't nearly as big of an advantage in picking Wii over PS3 as the hardware sales would suggest.
Lawl, the 360 has more RPG's for it than the PS3.
Maybe, but RPGs seem to be some of the longest-to-develop games, and 360 had a year extra. That'll probably resolve itself next year, with White Knight Story, FFXIII, Versus, etc. coming to PS3 and the 360 not meeting sales expectations for JRPGs (WRPGs are a different kind of beast altogether, really).
