Yes and no - I would argue that many good games sell consoles, and that if they're exclusive it helps for self-evident reasons. The SNES, for example, didn't eventually surpass the Genesis in sales because it had 'more' games (it actually had less; only 785 games were released on the SNES) but because it had a slew of classics, including varied brand names that were highly marketable - Mario, Zelda, etc. Still, games aren't all that matter: the Wii's sales were bolstered significantly by the novelty of its motion controls, and the hooplah surrounding the Xbox when it came out seemed to have more to do with the console's graphics than its software, short of Halo.
The Wii is the best-selling consule thus far, and has the broadest demographic - how do you describe that as 'cult'? I understand that its software library is an anamoly within the game industry, dependent as it is upon Nintendo exclusives, but you should be more careful in your choice of terminology.
How is that bad? It would seem to me a lack of 'family friendly' marketing caused the original Xbox to be pigeonholed as a shooters-only affair (which is, and was, wildly innacurate), and prevented it from becoming as mainstream as the PS2 - which was successful in part because it was able to bridge casual and hardcore demographics.
That's two games. The PS3 isn't exactly rife with exclusives, and until such time as it is games like Fable II and the Xbox 360's lower price will suffice as a counterpoint.
Why will 'other good games' be released for the PS3 because 'there are very few Xbox 360 exclusives'? If anything, the Xbox 360 is in a better position than the PS3 to attract exclusives because a) its hardware is easier to work with, and b) it's selling better, which means that games released by third-parties on it have the opportunity to amass more sales.
I don't actually disagree - the PS3 got off to a rough start by any measure, meaning there are alot of Sony loyalists who are apt to become late adopters (and moreso with each price drop), and the Wii phenomena will probably subside in the near-future. That said, I can't foresee the PS3 surpassing the Xbox 360 in sales unless it manages to distinguish itself as more than just an expensive 360 with Blu-Ray (admittedly a long-shot), save by prolonging its lifespan beyond its immediate competitors.
The Wii has shipped 35 million units and probably won't sell them off until Christmas, by which point the other consoles will have received a significant boost (the 360 is $199 now, remember). Moreover, I would argue the contrary - that the PS3 might surpass the Wii in sales because there's a good chance the Wii will be a short-lived console (I heard through the grapevine that Sony may keep the PS3 alive for ten years) and it's running thin on good will, but that it will have a hard time catching the Xbox 360 unless it manages to distinguish itself as more than an expensive variant.
In any case, I predict the Xbox 360 will win this round of the console wars - its sold 22m units and is entering Christmas with a major price drop (meaning it's not that far behind the Wii), is in good steads with the gaming community (something the Wii and PS3 often aren't), and has taken an early lead against the PS3 that seems definitive (the PS3 is having a hard time distinguishing itself), which will probably translate into a generational win once the Wii's momentum begins to erode - a natural symptom of the lack of excellent software it has out now, god bless it. Of course, Nintendo could just rush-release Super Mario Theoretical Region of Space and prove me wrong, but I doubt it.
