What exactly is concerning to you about it? Are you concerned they'll delay it? They've got so much official marketing saying March 20 that there's no possible way for them to delay it now, especially with the themed consoles having a set date as well. Aside from that, I don't think there's anything to be concerned about it. There's just a little over a month left to go, and it's an Animal Crossing game. The formula isn't going to be changed up THAT much that we need a ton of new information. Like I said in another thread, there's a coro coro magazine release on the 15th that's going to have an "exclusive scoop" on New Horizons. That will likely be the last of the information in February and maybe a few trailers in March.
