Sorry, dont normally comment on stuff like this but, if the game is delayed... you won't loose any money[unless it is cancelled] and buying the game again later down the line will loose you 2 months free sub. Surely the thing to do here would be leave it, and if it releases well sorted, you can play straight away. If it doesnt you can ride out 2 months free... cancel sub if it doesnt improve and just resub later when you want to try it again?
Or am i missing something?
