@GTV0819 what? I said games in 1994 were £40, games in 2001 were £40, games now are £40. Prices haven't changed significantly regardless of console generation, even looking at just Playstations - by your logic, if games were £40 on the PS1 then they should've been £50 on the PS2, £60 on PS3, £70 on PS4 and will be £80 on PS5, that hasn't happened.
The generational jump was arguably biggest between PS2 and PS3 (there was no price hike there) and smallest between PS3 and PS4. The jump from PS4 to PS5 will be even smaller for the same reason that generational differences between smartphones are tiny now, i.e. diminishing returns where the cost of making significant improvements beyond the usual incrementals of "more RAM, faster storage, faster processors" is far too high and isn't actually necessary because enough people will upgrade for them to turn a profit. As a result - and let's not forget the actual underlying platform is essentially the same, negating the need for any retooling in development - games aren't going to be harder to develop for the PS5, in fact they'll be easier because increased resources means developers won't need to try as hard to make optimisations.
If you think it was cheaper and/or easier to develop games on old consoles than it is now I suggest you do some research, this is a pretty good example of how hard developers had to push the limits of the devices they were developing for:
These days, developers have huge amounts of storage, H.264 codecs built into the silicon of the processors they're coding for and all the massively advanced video rendering and authoring tools. It has never been easier to make a game for a console, so I don't see any reason for prices to go up.
Nintendo is unusual though as they have much more control over their platforms than anyone else because of the gimmicks and novelty features they build into their consoles, whereas PS4, Xbox and PC are broadly compatible with one another; the controllers are the same, target resolutions the same, use cases, sharing features, hardware specs, processor architectures... They're very similar across the board. Nintendo's platforms aren't like that so they can and do do what they want without risking too much.
