Just to clarify, the SURPRISE is a completely different thing to the BONUS
The surprise is going to be worldwide, everyone will get it as long as they preorder. While the Bonus is a little something extra for the US people that have to wait, while it isn't as big as this very hyped surprise (Insomniac seem pretty sure this is going to be unmissable for any fan of the PS2 R&C games) Insomniac claim it's worth the wait.
i experienced the thing that when preordering All 4 One Special Edition it had the same price as the normal version. but on the relase date it changed the price to 17 dollar.. And i got it one day before the original releease date.. Unfornately the codes didn't work before the actual release date…
Insomniac Moon 2.0 is coming soon! Be prepared to have your socks rocked off!
