Nintendo has really abandoned their best selling IPs.

[68soul]

Nintendo has sold 50 million copies, thanks to only 8 of their Wii games released in 2008... i don't even mention DS games here... and you say they have abandonned their "best selling IP's"?

But they've done better than ever before! I think it's already an historical success... in fact, it's nearly unbelievable, when you compare them to anyone else in this industry...

And as most of their AAA titles take 2 to 4 years to be made, i think Wii and DS libraries have been treated the right way...

All the games you've mentionned are quality games, and deserve sequels, for sure... but seriously, they were nearly "niche successes" compared to the actual line-ups, you can't blame Nintendo for having other priorities, bringing them billions and billions...

Seriously, Nintendo has only 3000 employees, commercials and hardware engineers included... and none of these employees is paid for miracles: they work the best they can and can't do more and more "just like that", except if Nintendo creates new teams, or buys 2nd party teams...

A question to OP: would you have the budget to buy 2 or 3 times more games?

Just be thankful for what you've got... there are many ways to be pleased with Wii and DS, and there are three other consoles out there if you're still not happy... what more could you ask for?
