Amazon AU and JB have listed the PS4 version of Spider-Man Miles Morales for $79, $15 cheaper than the PS5 version at JB for $94, or the PS4 and PS5 versions at EB Games for $94.95. The thing is though, the PS4 version comes with a free upgrade to the PS5 version, so unless you really want that new white box art then the PS4 version is far better value. You could also potentially use this version on two consoles if you have a PS5 in your main home theatre setup and a PS4 in a kid's bedroom, where the PS5 version will limit you to playing only on the newer console.

Seems stupid to buy the PS5 version. Honestly, they took so long to drop a PS4 price I was starting to think it was gonna be digital only for last gen, this is good news.
