I can't really understand you disappointment, dear friends. What you are fearing, is one possibility. But it hasn't to be. So, the first thing to mention: it looks awfull good, also the gameplay looks better than ever for me. I know, many of you don't agree, but let't wait for the full release. Secondly, a cross-media plattform is a very good idea for online-fans - why should you be limited wainting for someone who has the same plattform as you? If this necessarly means that the quality it downgraded I don't think so. Thirdly, who said that offline-modes are dead? Nobody mentioned that. So, please be patient and wait for new announcements. If these modes will cost something as a DLC, why not? We always paided for the whole game, it depends only on the price, maybe it's even cheaper? and maybe they will do a really good ML? That's for me more important than the brand name, this is really not important, even if I am also getting sentimental.
But if on the other hand your fears will fulfill and there will be no ML, than I am out, of course. So let's hope for the best!
