Hopefully same day, Day one patches are a must with DICE. 
Oh god, please no more patches by DICE.
I swear to all things I hold dear, EVERY. SINGLE. PATCH. EVER. From DICE for Bf4 broke my game. I had to routinely uninstall, then redownload everything, install again just to play again, upon which most of the time DICE fixed some stuff, but reintroduced old bugs that were fixed and caused completely new bugs. Plus each patch so far required a couple server side stability patches just so people could reliably join servers and stop the game from randomly crashing all the time.
The fewer DICE patches, the better.
