It will release with one of three days.
Sunday, Tuesday and Fridays.
Tuesdays are normal release days for all companies. Nintendo and Sony have been having a lot of Friday releases lately so its not out of the question. Sunday releases have slowed down to a crawl but its an old standard release date so still possible.
So we have Sunday November 2nd, Tuesday November 4th, Friday November 7th, Sunday November 9th, Tuesday November 11th, Friday November 14th, Sunday November 16th, Tuesday November 18th, Friday November 21st, Sunday November 23rd, Tuesday November 25th, and Sunday November 30th.
Sales wise, the best dates to release are Sunday the 16th or Tuesday the 18th, the week before Black Friday. This gives all stores a chance to run ads and promote sales for the items. Hardly anything new ever comes out on the week of Black friday so we can exclude 23rd and 25th. For a safety mark they may release on the 30th after black friday if they feel that they cannot make the sales demand which many games never do.
So for optimum sales, November 16th is a good realistic date. Its a full week before black friday's sales. Gives a week to stock as well as run an ad for them. A week before that is also good so starting on the 9th is a safe guess as well. If they want to really just get numbers, as early as November 2nd is possible, but the best dates are between the 16th and the 21st with the 16th being the best for potential sales.
It's very likely that the release date could be the 21st, not only does that fall on the anniversary but it falls on a Friday which is a common mainstream game release day.
Nintendo's more common release days are Sunday and Tuesday. Friday releases are actually not that common.
This week, I think there are 4 games coming out tomorrow and only one game coming out this Friday. Minecraft physical copy for the PS3 is all I've seen coming out this friday in my store. The games that get Friday releases usually aren't large title games either. Friday releases are "ghost" releases. People don't realize the games were released.
