Updates are always coming "soon". Sorry, but only Playdom knows if and when an update will be released. We get teasers every now and then, but nothing more at moment.
ok, thanks for the info, just that I also play Real Racing 3 which has a 5 week update schedule, so I was interested to know if Alliance 2 had anything similar.

That was posted almost 3 weeks ago so I would imagine any day now..
