But by the time Nintendo put Ds-Wii into place there will be over 50 million DS's sold worldwide, and probably about 25 million PSP's. I mean I'm sure Sony could maybe sell some PS3's doing what you said, but they've certainly not marketed it very well and in terms of gameplay idea's I've seen nothing other then using it as a rear-view-mirror in a racing game (lol).

  What Sony are trying to do with PSP-Ps3 connectivity seems very nishe to me, I really don't see that many people using what you just described, whereas I think DS-Wii could be very different, depending on what Nintendo does with it. 

  I think for gaining sales DS is in a league of it's own in terms of connecting with it's respected console. Until Sony give it any sort of marketing whatever they try to do with it is going to go ignored.

What making it a small screen that plugs into the Wii and acts like a menu like what the did with the GBA-GC connecctivity

There is a lot of potential for the PSP/PS3 connectivity but it will never be used ...

The GBA and Gamecube offered a lot of potential interaction and yet failed for a couple of really key reasons:

1. Too few people owned a Gameboy Advance and a Gamecube to take advantage of this
2. It was too complicated and expensive to connect the two systems

Both the PSP/PS3 and DS/Wii have eliminated the second concern being that they are wireless out of the box, but the first one is still a big problem for both (and I suspect will be a worse problem for Sony). Until there are 20 Million people with the console and handheld I don't expect many third party developers will look into using the two systems together; this is a barrier that will take a long time for any company to meet.

The DS/Wii connectivity is about the only thing that makes Pokemon Battle Revolution remotely worthy of a purchase.

Hopefully Nintendo and Sony can take advantage of Wi-Fi and make games that relay on both.

  Firstly it's wireless.

   Secondly, I think if you can't see any potential in having motion controls coupled with two screens, a touch screen and a microphone while being connected to the internet simultaneously then you're just choosing to be ignorant.

 There are alot of ifs and buts about it, but I'm saying if Nintendo nail it 100% spot on. If they time it right, make the right software, allow for DS demo's via the Wii internet, maybe allow playing VC games on the DS as portable etc, then there could be alot of Wii sales to follow. Sony could benefit in the same way, but thus far they've really not marketed it very well and the DS is always going to have at least twice the market share (and thus twice the potential) to gain more console sales.

ID say Ps3s success is more because of.

GTA4
FF13
MGS4
Killzone2
Versus
Gran Turismo 5
LBP


It takes more then one or two great games,

The PS has motion,speaker,camera and can be connected to the internet and Sony are going to release Eye of Judgement which is kinda a step in the right direction and Nintendo did Pokemon Battle Revolution which is also a step in the right direction so hopefully the next game like these can use everything they have.

  Ds-Wii has far superior motions though, and also has camera and speaker (hell Wii-DS has the Wii Remote Speaker as well). 

 I agree both could potentially make for some great games, but I see more potential in DS-Wii (just my opinion though). It's really a matter of how they use it, I think Sony could end up shooting themselves in the foot if they try to show it off from a media viewpoint and not gaming. I don't personally see the PS3 gaining sales because it's a media centre, and that sort of focus could definitely ruin the entire point.
