I think everyone gets what you're saying. I certainly do. I don't see why everyone's jumping on you like you said something nuts.
On the other hand, it's true: none of the 3 consoles really fit the PS2's mold. The Wii has sales that roughly match it, although they started higher and look like they might taper off more quickly. That's clear, factual proof of what a lot of people think. But the Wii clearly doesn't have the continuation of many of the PS2's hit franchises or (decent) support from many developers. The PS3 would be the obvious choice, except that it's drastically underperformed and so many franchises have become non-exclusive. The 360 is kind of left by default. It has the best-selling versions of a lot of last gen's hit franchises, and some new ones as well. But it's still no PS2. What the PS2 had is fragmented.
So, sure, a lot of people's answer to that question might be the 360. But the market is so compartmentalized now, you might be surprised: to the general public, the answer might be the Wii (or yes, DS). Some people might go off the wall and say the iPhone. Some might say Steam. I'm sure a lot would say PS3 because, duh, it's one number higher.
I know what you're trying to say. But I think you're taking that answer for granted, too.
