Hi,
the game is going to be Free 2 Play.
The beta settings on your account will be wiped
Everyone will start at 0 with just 3 tier 1 tanks.
However, the you can buy Gold (Premium Account) through micro transactions.
Last time I looked there was no fixed price, but I think something like 2500 gold for $10/10Euros was mooted
