There have been rumors in the past of Games Days going away or scaling down. The latest rumor along these lines is that the US Games Day will not be happening.
Please remember that this is a rumor. Definitely add some salt to this one.

A friend who worked for gw for quite a few years was talking to a old acquaintance still there and he mentions the 2014 US gamesday most likely wont be happening. This is from a friend of a friend so it needs to be taken with salt but keep a eye for this development.
