Guerilla has 2 teams? Then why are there 4 year gaps between games? 
Even so, I doubt it. Looking at KZ sales vs Horizon which arguably outsold the entire KZ franchise with one game, it’s clear Sony knows what their fans want. “Single player story driven 3rd person action adventure”. Seems to be the main recipe for their top games. PS gamers seem to not get enough of this so a FPS seems out of the cards right now. 

Days Gone sold well enough, I wouldn’t worry, Dreams is another story. MM spent what, over 5 years making Dreams and I’m pretty sure it bombed almost immediately. Too high a learning curve for mass appeal and to be blunt, Minecraft holds a firm monopoly on the “Play create share” genre. 

We have no idea if it "bombed almost immediately"... not to mention first week sales weren't as high as they could've been since it had been in early access for quite a while too, I bought it MONTHS before the official release and put in a solid 200+ hours before launch day, lol. As for the learning curve being too high for mass appeal I'd argue that it's the complete opposite... there's more to Dreams than making an entire fleshed out game, you can paint pictures, sculpt, make music, animate, make videos, or just make memes... it's ridiculously user friendly, the only thing I see people complain about is the controls feeling weird while creating, but after a couple of hours it all comes naturally. 

Sure we don’t know but that in itself doesn’t bode well. No Sony PR touting its sales reception, and it’s a $40 game. First week sales by your own admission weren’t high and usually sales drop more in week 2, etc. Overall it wasn’t marketed well. 

I’m not knocking your experience with the game, merely it’s profitability. Whatever numbers it’s pulling I don’t think it was worth the 6 years in development. They gotta pick a new genre imo 

Bot Bend and Media Molecule are fine. Day's Gone has been mentioned in the past few PS financials as helping boost profit gains around the time of it's release.

I can see Studio Japan helping another team make PSBR2. But they didn't spend the PS4 gen working towards that I feel. Their goal is def towards becoming a Guerrilla or Santa Monica esque studio. The Silent Hill rumours point towards this (that is if it's true)

There's nothing to be concerned about. MM have been consistently making profit ever since the release of LBP. Their financial statement ending Mar 2019 reveals profit for at least the last 3 years. This was before the release of Dreams Early Access in April, and the final release in Feb 2020. Older statements receal profit earnings.

People seem to always think that MM is in some critical situation when in fact they are a finally secured studio.

How would that be possible given their last title LBP 3 released in 2014?
