Let's see here: Killzone is essentially dead, as Guerrilla Games has been focusing on Horizon Zero Dawn. It has said in interviews that it hasn't ruled out another game in the franchise, but after the last one received middling reviews, I wouldn't count on it, unless HZD similarly tanks. The last game is older than GT6.
LBP3 was a shoddy game compared to the quite excellent LBP2, probably due to Media Molecule moving onto Dreams and handing the franchise to Sumo Digital. Tellingly, it sold quite a lot less. Infamous has similarly flickered out over the years. Rumour has it Sucker Punch is working on a new IP, which I imagine we'll first see at E3 this year.
Detroit and Days Gone aren't even out yet, and
@Imari's point was about "brands". These are the starts of new IP's: they're not established Sony brands yet. The Last Guardian almost is (okay, Team Ico), but from what I've seen of reviews, it didn't live up to the hype (which, to be fair, was expected: nothing could after almost a decade of teasing).
I think it's fair to say Uncharted is Sony's biggest "brand" right now, on a global scale. Naughty Dog is also a dev with the closest thing to a blemish-free CV: it's simply gone from strength to strength, and that looks to continue with TLOU2 and the Uncharted 4 expansion. Not even PD has the critical record Naughty Dog has.
Switch conference just ended, its a joke. PS4 will annihilate it.
In terms of power under the hood? Yep. Sales? Almost certainly.
But it will still be the biggest thing in shops the week of release. That's something one wouldn't want to launch a game against, even if there isn't a lot of cross-over shoppers. It's a bit like Fox or Universal scheduling any bigger movie around mid-December; they very much could, but now that Star Wars has planted its flag around there for the near future, it'd be stacking the deck against themselves in terms of publicity against the Mouse House.
Ahem PS4 sales, shows none of that really matters.
This is a great example of moving the goalposts.
As an aside, you'll want to have a re-read of the
Acceptable Use Policy, specifically the second bullet point. 👍
