This will blow over, almost everyone upset by the online thing will still buy the console. This cycle has happened before and will happen again.
I don't think so at all. I think now more than ever with the massive amount of information that people have access to, you have to actually sell your product better than ever. People are learning that devs will smile and paint a pretty picture and than just release crap(Aliens, WarZ, etc.)
COD is consistently the highest selling franchise because people know exactly what they are getting, not what they aren't. You(and me) may not agree with the content, but if your interested in a product you have videos/articles/podcasts/forums/walkthroughs/etc. that can essentially tell you exactly what the product is about.
I'm not interested or impressed in what I've seen of the PS4, but I know that a lot are because the access to information for it is pretty solid and people can make a decision for themselves in regards to a purchase if they deem it to be something they like.
720 info will start pouring out very soon and people will be able to gauge exactly what to expect from it just the same. PC gaming is more popular now than ever before and there are too many games for me to choose from, I have the benefit of Youtube being able to tell me if I will like something.
Though, I did buy Alien:CM. It was a beautiful bait and switch and I've learned my lesson. I was part of the problem.
