It's a 2 part interview held with BBs at this year's gamescom event.
You'll need to translate it from German, and read between the lines, unless you can read/speak German of course.
Here's a summary of the more important stuff I gleened from it.
(there's more, stuff that seemed less important, or stuff i didn't quite understand lol)
* The new combat system includes first PVP features. (new islands? new types of troops?)
* barracks: train 25. technical issues prevents current change, but it's being changed with the new system
* tested features on hold due to technical problems, but they will work on them in the future:
rock demo
guild bank
*things they can't change because it would result in too much lag or there are technical problems
destroy trees,
news menu,
bookbinder que,
star menu stacking,
stacking buffs on a building
stopping a geo/explorer after search has started
mobile version of the game would require a total rewrite
*things on their list of: to be improved
adventure loot straight to mayor house
high number of advs required for guild quests
ability to open trade window and warehouse side by side
adding new buffs to artifact search, which will reduce finding fish/sammie buffs
adding numbers box to trading
changing guild coin market more often, adjusting prices
changing quests so they dont require the small buildings when we have bigger ones (brewery vs friary)
