I’m sure From is very happy with how their wedding is going with Miyazaki. Krueger built Housemarque to be one of the most interesting and fresh devs out there. This is the darkest day for PlayStation. Krueger was showing us you could still gamble high production values and leftield non-mainstream ideas.
Language is a major barrier for most Japanese devs. Which is why its extremely rare to see them move outside their home nation.
For someone like Krueger, who is fluent in English, the success afforded by Returnal will have opened up tremendous opportunities internationally*. Frankly, in that position he'd be foolish not to take advantage of a literal chance of a lifetime to improve his and his family's lot.
The alternative being sinking another 4-5 years of his career into making a follow-up at Housemarque and hoping to maintain/build on that success... which even under ideal circumstances is never going to be a certainty.
Seriously dude, think about this stuff from the perspective of the individual concerned, not like they are just some corporate widget.
*His first job I believe was at Q-Games in Kyoto. So even Japan would be a possibility.
