No way. It will a while before inventory reflects this. Just like when a new OS comes out, computers in the store were manufactured and distributed prior to the OS roll out. Give it 2-4 weeks before that happens.
I called the store here in Columbus Ohio and asked if they were going to upgrade their floor model today. I was told the update is not available today and no they were not going to update today. LOL I guess apple doesn't want to sell me one today. What a joke apples customer service is. I even had the person ask the supervisor of the store and got the same response.
I've been sort of waiting for the new packaging as well...just on the vague chance something gets quietly updated (99% unlikely, but I'm waiting to pick up a Time Capsule as well, and was planning on waiting until the potential mystery end-of-February surprise event came and went)...
