I think Nintendo is more interested in growing the DD marketplace for third parties. That's why VC releases have been slow, and especially new Nintendo games on VC. It's a strategic decision to attract new developers to Nintendo platforms rather than just earn more money off of old games. They want to draw in fresh talent and ideas and get them comfortable with Nintendo hardware and market ideas. Every VC release draws attention and money away from new developers on WiiWare.
So if FADE is accurate, World of Goo has made 2D Boy returns of $32 per dollar of original investment in the NA Wii market alone. Then you can stack on PC sales and other regions. No wonder there's a gold rush on DD platforms. The potential returns, even just for two dudes with a great idea and some experience, are staggering.
"The worst part about these reviews is they are [subjective]--and their scores often depend on how drunk you got the media at a Street Fighter event." — Mona Hamilton, Capcom Senior VP of Marketing
