With the release of 0.5.2 update for World of Warplanes open beta.
Now you can earn tokens in WoWP and use them to purchase unified/single premium account for both WG games currently being available - i.e. "free" WoT prem accounts are now available.
It's farming time!
PS: EU guys, sorry for the communication issue and absence of proper announcement on what was going to happen with tokens.
