Source: RU forums You will like this, guys! Evilly (RU main community organizer): - all the users, who had top engines on either E-75 or E-50 unlocked, will recieve 25000 free XP on their account in 8.8 (you will get this free XP even if the tank isn’t bought in the hangar, you will get free XP only for one, so even if you have both unlocked, you will get 25k, not 50k, because the engines were identical and they were unlocked once) - ALL the engines that are unlocked, bought, installed on vehicles will be sold for the price they were purchased for when 8.8 goes live - new top E-75/E-50 engines will be unlocked for those, who had previously the top engines unlocked - Superpershing will be possible to sell for gold purchase price in 8.8
