Please note that this is the PC Steam Key version of the game, a Preorder version, not the PlayStation version of the game. Any one who have PS5/PS4 and PS PLUS can get the game for free on PS PLUS now in this month. But this is the PC version of the game that has extra features like Ultrawide Support + Higher Res Textures + Uncapped framerates etc.
To see what is extra in the PC version, see this Youtube video : https://www.youtube.com/watch?v=tgpTNx7bdFw
Normal Steam price is AUD 74.99. Once you see the link, you have to log in (create a free account if you don't) and will see that the price is AUD 62.99. Use the Coupon Code SPR21 to bring the price down to AUD 59.99. Game unlocks on May 18th (so possibly May 19th in Australia).
So your money, your choice, get the game for free on PS4/PS5 if you have PS Plus or else this is the cheapest price for the PC version as it stands today that gives you extra PC specific features.
