Mate, if we like it or not, this is entertainment. It's a luxury toy basically. So yes, they do expect us to have 2/3 jobs to pay for it, or buy it down the line, etc. We're not the main market.
I'm from Portugal (PORTUGAL CARALHO!!) and our minimum wage is 680€, there's no way in hell most people here can afford a console at launch without proper saving for it, but it's not like selling 50 000 PS5's here will majorly impact Sony's numbers. Hell, we don't even have 1/3 of the functionalities and apps in the PS store that people in the UK have.
