Some might find it entertaining, this joking about what week/year the next patch will be released.
I personally am quite ticked off. Paid $75 for the -300, (25/04/16) got 2 friends to buy it as well. Most I ever paid for an add-on.
And while the plane itself looks quite good and I feel right at home in it. (I fly it) The FMC is nowhere to being really useable. Adding fixes, restrictions, holdings.. Nothing works.
So please get back to making this a $75 worth of add-on.
