I don't think anyone has countered this yet, but I'd like to point out that Nintendo has been eagerly trying to patch things up with third parties ever since the N64 failed.
Any third party who's still upset over the things Nintendo did during NES/SNES eras should just get the fuck over it already. Nintendo has learned their lesson, and the developers know that. Nintendo has been reaching out in more than one way (I think even going so far as to lending them employees to help with efficiency with the Wii).
Third parties aren't producing shitty games because they hate Nintendo or Nintendo is limiting them. Third parties are producing shitty games because A) They are fucking lazy and B) Everyone underestimated the Wii at the start, and had no great software in production.
Anyone who's smart about making money has already started putting effort into the Wii and we'll see those effects late 08 and early 09.
By life end:
- Wii- 100 million+
- Xbox360- 35~40 million
- PS3- 30 million
- PSP- 30~32 million ------------- FAILURE
- NDS- 85~90 million (Skeptical) - FAILURE
- NDS- 100 million+ (Optimistic) -- Success!
