Crossing the fingers for that.
I guess it will take some days, but I believe they will fix it in the end.
People I know just bought BF4 Premium recently and DLCs maps are part of it; it cannot be that EA just sells something knowing that it will be retired after few weeks.
I am sure EA management doesn't want to take another hit from an angry fanbase.
Remember the line for the BFV "If you don't like it, don't buy it", and what happened next?
Well, I believe they still remember that ; -) In around 2 month or so. EA stock sinked from 120 USD to 80 USD.
Nowadays the company is recovering and doing very well, especially because they announced the new BF is in work -and it will be back to successful BF4 style, gameplay and glory.
EA has finally listened to the fanbase: Exclusive: Vince Zampella Confirms Next Battlefield Will Use Modern Setting, First Concept Art Revealed
That is why I believe they will fix it guys, I don't know it for sure, but I have still faith in EA to take the right decisions.
Just let's give them still few days ;-)
Possibly next weekend we'll play again with DLCs and all other extensions.
