Here's the original interview for some context:

He only says that they've stopped supporting the original Xbox. In fact, he's rather adamant about it: "Xbox is done. Version 1 Xbox is totally done. They haven't announced that it's over but believe me, it's over. That category is gone. There will be nothing new from us for Xbox." However, they haven't ruled out doing anything for the 360 yet. Live Arcade is mentioned, but Mr. Herman doesn't sound too enthused about it.
You definitely get a sense that he wants to support Wii the most. He brings up the high development costs of the other systems and the 360's lack of a consumer base in Japan, as well as Sony's aforementioned anti-2D stance, yet generally only has nice things to say about Wii. When asked about getting SNK classics onto the Virtual Console, he says, "I am not going to hold back." It'll be interesting to see just how much they'll support Wii.
There's also some interesting stuff mentioned about Nintendo actively telling developers to create accessories for the Wii. For some reason, I'm really itching for a chainsaw shell for Resident Evil.
