For the same reason people speculate over and share rumours about the new graphic cards that are going to be released this January: hype.

Might want to enlighten us by telling us the plot of W4?

No corporation is too big to fail.

MCI Worldcom

Pepperidge Farms remembers.

With our luck (like with Disney)? Probably not.

People have been speculating about the Switch 2 since the Switch 1 was revealed.

Should take bets then. Makes more sense than accolades. I wouldnt. But it makes sense to me to do so.

Those are two interesting points you raise.

Firts one, blood ties. On paper gog and red are sister companies under cdp's fatherhood. In reality cdp seems to be a mere non sentient blanket with cdpr as the "de facto" dome, so from that prespective, yes, gog's parent company - red - is the developer of TW4.

Second one, money flow. All i know is that 100% of the revenue of red games pushed though gog stays underneath the cdp umbrella, but how does what we've come to refer to as "extra" revenue flows between sister companies ? Does it stay within gog ? All of it, a part of it, none of it ?

So basically what the OP is asking is can Gog get by financially if Witcher 4 doesn't sell well?

Steam and Gog probably don't have much expenses in general, it's basically a server, Galaxy updates and what not. Maintenance. In theory gog should be able to skate by on a shoestring budget because what do they actually need to do? Devs do the work, sites like Gog and Steam kinda cash in in a partially unearned sort of way, especially at a 30% cut that I think I heard it is.

Unless they went into great debt making Witcher 4 and would try to extract it out of Gog if it flopped, I doubt they could though.
