Probably not that high.

But definately a higehr ratio of Wii Remote+ Controllers to the Wii then thier are Vita and PS3 owners.

Of course a Vita/PS3 can do that. Wait till Sony, if ever, makes a game from the ground up for cross-controller before saying the Vita/ps3 can't do something. Your evidence is just from a couple minutes with a single demo* for vita/ps3 verse a whole launch lineup with extensive demos for Wii U. Hopefully LBP cross-controller will offer enough tools for these features to be demonstrated by the community.

*I really don't consider PSASBR to belong in this discussion. Yes the vita can be used as a controller, but that is roughly the extent of it. In no way is it aiming to be what the Wii U is.

:D as if the Vita can do everything the GamePad can do.
Just because they can do a few features they go all crazy about it. The games I play on PS3 don't even support dual screen gameplay or streaming. They just come up with it now after it is being brought to the market so they don't need to do all the PR work.

I dunno, if VGChartz's data on Wii Sports Resort is accurate, at LEAST 30 million Wii owners have at least one WM+. On top of that, I'm pretty sure the more recent Wii hardware (past 2 years or so) has been bundled with Wii Remote +. I don't think it would be a stretch to suggest that 40 million Wii owners own at least one Wii Motion + or Wii Remote +. The real question is, how many of them own multiple? Or, basically, what is the actual adoption rate of Motion Plus compared to Wii consoles and especially compared to original Wii Remotes?

But yeah, definitely WAY more Motion Plus owners per Wii than Vita owners per PS3...

My claim is based on evidence we've seen so far whereas yours is highly presumptuous.  And I'm not talking about something incredibly simple; I'm talking about a full-fledged PS3 game displaying simultaneously on both screens and with only one game running, ala my examples above.  As of now I am skeptical, as the PS3 was not designed around this streaming functionality like WiiU was, and I stand by my claim, plain and simple.

And yes, PSASBR does factor into this discussion as it futher goes to my point that the Vita must be running its own, separate game for it to work as it does.

Yes yes, but only 1% of PS3 owners have a PS Vita so it doesn't compare to 100% of Wii U owners having a gamepad.
Integration is not feasible with such low % cross ownership.

Again wait till you know details on why it can't do something. You are saying Vita/PS3 can't do things only because you haven't seen them done. That is like saying China doesn't exist because you haven't been there. So why don't I buy you a plane ticket so you can see for yourself?

You have no idea how long this took to find since Sony kept changing the name of cross-controller but here is a video from TGS 2011. http://www.youtube.com/watch?v=sGyVA5OUoEg Way back then they had it working with both the TV and Vita screens displaying unique PS3 quality graphics. Your first point "Can PS3/Vita cross controller play display Little Big Planet 2's full screen PS3 graphics on both the TV and the Vita simultaneously?  Nope." is wrong.

Sadly your second point I do not have any concrete evidence against. The best I have is my Vita and this video. http://www.youtube.com/watch?v=Xj8b1HRAY4s as well as an official pdf. In the video you can see he is playing as player one with two other local players. This at first shows he is doing cross-controller and not cross-play. The fact he is player one really goes against the thought of him joining a PS3 game instead of playing it. This agrees with https://www.scei.co.jp/corporate/release/pdf/120605a_e.pdf saying that "The Cross-Controller feature allows a player to use PS Vita as a controller to play games on PS3®, by utilizing its rich features including touch screen, rear touch pad, six-axis motion sensing system, and cameras.". Nothing in the pdf states or even implies a Vita game is used. But this pdf is outdated so their plans "could" have changed. In addition within the Vita's menus cross-controller is located under remote-play, not say LBP PS Vita. This again supports the notion that only the PS3 version of PSASBR is needed. Other games also don't need a Vita version. For LBP don't you think it would be strange if they allways called it LBP2 cross-controller if you needed LBP PS Vita too? Do you have any sources suggesting otherwise?

1.  First off, saying, "Of course a Vita/PS3 can do that" is no different.  Assuming that China doesn't exist becasuse I haven't seen it first hand is an absurd analogy, as there is at least overwhelming evidence that it does.  Speaking to my claim, there is not one shred of evidence supporting what you're saying; at least not yet.  Which brings me to your second point...

2.  Is it wrong?  I have a feeling that the video you provided is just showing the Vita screen twice.  There is never any indication that the screen on the left is the TV running at the same time.  I see why you would assume it was, but I think they are just showing a direct feed of the Vita screen on the left and filming the handheld itself on the right.  I could be wrong, but again, the evidence where you actually see both screens on display shows otherwise:

Notice how the Vita is displaying only simple shapes while LBP2 is running on the "TV".  When Sackboy enters the pipe near the end, the action switches to the Vita while the TV screen stops.  This video was from Gamescom only a couple of months ago and none of the floor demos from the show prove otherwise.  So no, I'm not convinced that the PS3 can stream the game to the Vita while still maintaining it fully playable on the TV.

3.  Regarding using the Vita as a controller for the PS3, that was never in question, so I don't know why you brought that up.  As for that video, the Vita could very well be running PSASBR along with the PS3.  If it isn't, then that would at least prove that the image is being displayed simultaneously, which I will admit that there is some credibility there, but as of now we don't know (or at least I don't).  Sony is wisely including the Vita version of the game with the PS3 version, which also adds weight to the assumption that both versions are needed for cross-play. 

And this is to say nothing of the fact that COD: BO2 for WiiU is actually supporting the game independently on both screens; not just outputting the same image to the controller, but providing that player's full independent view of the level.  So again, I stand by my claim that it's questionable if PS3/Vita is capable of easily replicating what WiiU can do as far as the console game running simultaneously on both screens and with only one copy of the game.

Provided you own a vita........

Wasn't this supposed to be locked?
