The commercial is very clearly targeting the fact that the storm (by counting lightening and thunder separation) is coming closer. No doubt they're doing this to signify the Thunderbolt is coming closer. Now whether or not the counting is directly related to the release being 3 days away is definitely reading into it but not unreasonable by any means.
Not sure if everyone missed when the commercial was first posted on the 15th... http://www.youtube.com/watch?v=A9h_Klwueks
So OBVIOUSLY it isn't suggesting that the phone is 3 days away, because that would have meant the 18th.
Everyone is talking about the commercial with the counting, as if it really was JUST released.
Originally, that commercial was in Spanish (they seem to have taken it off of their channel) and at the end, it said "Februaro" instead of "Coming Soon"
