i have no idea if i will get it or not at the moment, but i agree its far too soon the last expansion pack will barely have been released by the time bf4 is released.
I just find it really annoying. I was lured in by all the hype and fanfare of the premium pack, which exceeds the cost of the original game, now only to find out that this will be superceded soon enough. Battlefield 2 had a much longer life cycle than this one. Ea sure now how to rake in the money!!!
But they've looped it through some game called Medal of Honour something or other, to boost the sales of that game as an anticipation building exercise. So, I suppose BF4 may be in a similar vein to Medal of Honour rather than just an even more glitzier version of a dying concept.
Saying this, I am wrong sometimes...
Just be a nutter... life becomes much more exciting, and people won't expect anything more of you...
