Here is a post Nimhain made a couple weeks ago to explain the change in the rate of troop releases. I read this as saying they are going to be maintaining the current pace at least until the 2.2 update is approved by Sony and Microsoft (to avoid the problems we had before Christmas where they were running out of available troops to release). After that, they can get the last little bit of catching up done and get the troop releases synchronized. As of now, there are five available weekly events from PC/Mobile version 2.1.5 (Zaejin, Pridelands, Leonis Empire, Khetar and Darkstone), so they’ll need to get the 2.2 update out in the next 5 weeks in order to proceed according to the new plan. They need to push the planned events out way further into the future than they had before so that they can deal with unexpected delays without any hiccups once they are trying to update all platforms at once.
I haven’t seen any hints as to synchronizing game features (customizable AI and daily tasks for PC/Mobile; weekly events, etc. for console; guild wars for both).
