For Amazon Prime people: I noticed recently that some of my pre-orders had the WRONG SHIPPING OPTION on them, and that might have been the reason why some of my Prime orders have arrived late. Wipeout Omega Collection and Yakuza Kiwami both had "Express Shipping" selected, but that's slower than "Two-Day Shipping," which is free and seems to do the release-day shipping thing. Wipeout Omega Collection shipped yesterday night and should be arriving today as a result. I'm not sure why this happens; Wipeout was ordered before the Prime discount was applied on the store page so that maybe explains that one, but not Yakuza Kiwami, which I ended up re-placing once the Prime discount was applied properly.
tl;dr Check your orders and switch to Two-Day Shipping if you need to!
