Depends on where you live. Some Best Buys are getting them and putting them out tomorrow, possibly even tonight if they get there soon enough. Most EB's are same-day shipping them and will have them for sale tomorrow afternoon or night.
I don't think this will be a MGS3:S LE situation, nor do I think it will be a Jade Empire and Halo 2 situation. Maybe a True Crime: NYC or NFS:MW Black Edition situation. It'll be widely available for a few weeks, then disappear.
It's starting to seem like there will only be one shipment of the CE, though. I don't want to start any rumors or anything, but i'm thinking it'll be a "We got a few in, but once they're gone, they're gone".
MGS3:S LE was just insane. 2 LE's per store? Pfft.
