Unfortunatley, I don't think the delay has anything to do with any patch. I believe the reason for the delay is that they want to release it in whole Europe at the same time, and some of the local language versions hasn't been finished yet. So they don't want to release it in England (or here in Norway where we get the English version) until they have Italian, German etc. translations ready.
To look at the bright side though: This hopefully means that there is a new patch ready for download when the game is finally released here.
