...right, until Sony releas's a new system after the PS3 that is [hopefully] backwards compatible with a low price point.
I can ensure you that if Sony releases a new Playstation bundled with a camera, and some advanced motion sensing stuff (similar to what they have shown in tech demo's on the PS Blog and in patents) they will most certainly pose a serious threat to Microsoft unless Microsoft makes some big changes in the way they approach gaming.
As much as you may crave another upgrade, the companies that do minimal upgrades will be the ones that will be most successful next generation.
Obviously motion sensing technology was the big thing this generation that brought people in, and next generation it's going to be the combination of motion sensing and video. A controller and camera that can detect motion and general position together will over that next level of interactivity (as well as simplicity). The biggest hurdle will be accuracy.
That said, Sony has been working with both for some time, and I think it will be pretty easy for them next generation. I entirely predict a low spec PS4 to be slightly more powerful than the PS3 (basically a beefed up PS3) with a bundled HD camera and a new controller type (possibly the breakaway controller we've all seen).
But to say if MS get's a "headstart" on them, that they can cause Sony to never gain a foothold again? That's really really...ridiculous.
I think you're totally mistaken, because like so many do I think you're not understanding the two markets. The two markets are hardcore, and casual. Wii the latter, PS360 the former.
Hardcore is a huge market, it made videogames a gigantic business and sold 140 million PS2's before the Wii came along, even today the software and hardware split if you add Ps3 and 360 together versus Wii is close to 50-50, not Wii domination. Lets look at vgchartz, we all know their numbers are suspect, but for overall WW sales theyll closely track reported shipping, and they currently have Wii 46m, 360 28m, and PS3 20m. So theoretically there are slightly more hi-def hardcore consoles in the world than there are Wii's (granted that the Wii has been supply constrained in several territories).
Anyways, graphics are very important to the hardcore gamer crowd. And any company that wishes to target that market ignores graphics at their own peril. If they wish to cede that market, fine, but that market isnt going away, probably ever, and somebody will tap it.
I have my doubts that Sony or Ms could succeed in the Wii's market. There was an interview I read with some MS figure, probably Bach, and he laid it out, they dont have the IP to do what Nntendo does. They have Halo, they dont have Mario. I dont see that having changed since then.
Like I say, if MS or Sony wants to try to do what Nintendo is doing, I suspect a big flop is in the offing. At the very least even if they did succeed, like Wii is currently, they'll be irrelevant to me. Wii can sell a trillion and it just doesnt matter to me.
That is why I think for example, Sony is exactly right when they say Wii isnt competition to them (and MS has made similar statements as well I'm sure). People want to laugh and hurr hurr, but they get it. 360 is their competition, not Wii. We on forums seem to intuitively understand this of course, the big "rivalry" is between Ps3 and 360. And of course on forums, we are the (relatively) young, the male, the hardcore.
