The PS4 will follow a similar sales trend to the PS3

I think there are a few things we can be pretty confident about.

I don't expect it to be sold at 300$, that was the Vita's price with Mem card, and this is something much greater than the Vita, if HW speculation is any indicator. I don't expect it to be sold at 600$ either, as that was a failure of a price, and they will never repeat that mistake, not in a million years.

So there are some things we know.

Then, we know that devs have been much more lovey-dovey with Microsoft in general, the exceptions usually make exclusives for Sony. Multiplats are usually more xbox friendly. This is above and beyond the fact that the xbox has 1.5 times the marketshare PS has in the US.

Then, what exactly could boost PS4 sales above PS3 sales that hasn't been confirmed yet? I know one being that they may have a more effective strategy to target the mainstream. That's 30m units more, since there is competition from MS in that market as well, let alone Nintendo.

We also know that the core market caps at around 80-90m units sold, and that's with remodels being released.
