They aren't taking two months to update. Per rule their updates takes 30 days +/- each release, without drawbacks. However, every release there are bug fixes, so it takes 3 days up to a week to fix. If you do the math, every 1 month and few days, looks like they've been delaying to much, but not really.
Take last time's release for instance, they took a week and half to do whatever they were doing with the game. They released around 15th of last month i think. So, basically we're in the final touches week
