According to Konami, the patch was "cancelled due to technical issues and resources."
Just a reminder to everyone that you have rights as consumers and if a product sold is defective then you have the right to demand a full refund. Don't accept this kind of thing if you got a glitchy game and held on because a patch was coming. If you are told you cannot get a refund then talk to your local equivalent of the Citizens Advice Bureaux about what rights you have to recourse based on being sold a faulty product. It's only because they think they can get away with it that Konami is doing this, make your voice heard by getting your money back and pointing to this reason if required to explain your return.
