They said only that with friday update Dragon Balls will be implemented and You will be able to drop them from mobs to gain Your second HTB skill and transformations.

This is how much I understood in it, but tbh I didn't knew that second HTB needs dragon wish to obtain

I knew that, there is guide on gamemeca showing all wishes and HTB is one of them.

That's friday as in last friday or the upcoming update?

Friday as in tomorrow. The only change for that patch is the Dragonball drops and I think some bug fixes.

So dragonballs after 20 weren't able to be obtained? Good to know.

Information about when to expect the first set of updates has been released and the first post has been updated with this information. Items in bold represent new updates that were not originally announced, but were included in the schedule.

Some pretty nice crafting updates coming :)

Gamemeca has also released an interview with NTL about some of the high level updates:

They talk a little bit about the Nimbus, but say that they must first deal with some technical problems concerning it. The only other new piece of information seems to be about this new PvP mechanic. I can't really make much out of what they're saying about it, but it seems to involve people killing each other over collecting the Dragonballs.

Also, The Engineer class isn't dead yet. They still have plans to release it eventually.

Yeah, cool updates, the chips will be the best. x]

Schedule was tweaked. Almost everything was pushed back a week. First post has been updated with this information.
