why so desperate to see new harware with no many games to play with, the DS is selling a lot, Nintendo would be stupid to release another one right now, they will wait until sales start to decline, probably 2010 or 2011

I doubt they will release the new handheld in 2011, probably 2012, E3 2010 they'll show off the Vitality sensor, so E3 2011 for the next handheld, then released the year after holidays (2012), and the year after for the next console (E3 2012) and then release it the year after (2013) at the holidays.

I think one of Wii 2 or DS2 will be out next year for sure at least in Japan.

DS has hit a saturation point in North America and Europe I think (sales are down this year despite DSi).

I don't know if you want to give Apple years and years to continue upgrading the iPod touch/iPhone line with more games while you just stand pat either.

I think it's also pretty clear Nintendo is accelerating the rate at which they introduce new handheld models. There's pretty much a new DS out now almost on a yearly basis ... I think they are moving more towards an Apple like model themselves.  

I'll go with Kantor: I believe that DS's true sucessor will take a bit long now. I bet 2013-2014.

2013/14 is pretty ridiculous considering they're releasing more hardware revisions now.

I think they are actually testing the market to get them used to having more and more iterations, just like the iPod.

By the end of 2011 I believe both the successors to the current DS and Wii will both be on the market.

2011 +

nexg gen consoles

2013 +

When they have another system ready, they will make the successor. They likely would want something worth having a new system over instead of just stronger specs.

2015 would be the year it comes...
novermder would be the month
and the day would be 27...

but im just guessing...

I would bet they have both the Wii 2 and DS 2 complete already hardware wise pretty much more or less.

That depends on if they simply want more powerful systems or a further gameplay control setup. If the latter, then they need to have the ideas come to them a while ago to have the systems complete. Just assuming they are complete is wrong, since systems can often get changed up until near the last minute.
