I don't think T-Mobile would even care about something like that because the only people getting crazy about the pre-orders not shipping out early are people that go to this website, XDA Developers and so on. The majority of people will buy this phone after seeing family, friends and co-workers with them because lets be honest...most people don't even know about this phone (at least in America). The only time I saw a news story about the Note 7 was the release date and even then it wasn't on most major new websites (non-tech websites), I haven't heard anything about it on the news since announcement date.
I can't wait for my Note 7 in black but I wouldn't be shocked if I didn't get it until next Friday which sucks, I'm a nerd when it comes to phones but 95% of people could care less to be honest. I worked at AT&T as a sales rep for 7 years and trust me besides the iPhone most customers (except for tech nerds) could care less about launches and especially pre-orders.
I really hope T-Mobile ships them today or tomorrow!!!
