On the "Wii sales aren't driven by games" and "what games are people buying for their Wii's"...um, are people ignoring what games numbers 2, 4, 7, and 8 in the top 10 are? You have one game (okay, "game") selling 370K copies, another selling 284K copies, and the last two selling 175K and 165K copies respectively, for a total of about 1M software unit sales in the top 10 alone, with who knows what selling in the top 20/30/40, and people seriously ask, "What could possibly be selling 555K consoles a month? THE NUMBERS DON'T ADD UP! I don't think people are buying Wiis for the games!"
I'd say the Wii is the only console where you KNOW every sale is driven by the software, because it certainly isn't selling based on its BluRay / Netflix / multimedia hub capabilities.
