Basically, what he wrote is that we can expect some more "bombshells" of the "same magnitude", as the stuff revealed today in the patch 0.8.6, that will be revealed next week. Storm mentions changes "game economy and balance".
As always, Storm was (well, is even at this moment) posting in the comments. Info from those comments:
- these changes will be uncovered the following week
- Komarin and Swamp is atm in the process of re-work (won't come in 0.8.6 apparently)
- camo values for tanks won't ever be disclosed
- SU-5 won't have bigger ammo capacity - quite the contrary, WG will make it smaller, but the shell damage will be buffed
- reworked fire extinguishers won't come in 0.8.6
- the economy changes will "hurt"
- Storm would like to tell the players more, but this info has to be published steadily because of translations etc.
