Now knowing that digital purchases on all three systems are not going to be carried over to new system, I think I'm going to use Steam exclusively for multi-platform titles (I don't know what Im going to do about EA titles yet). I will still end up buying all three systems eventually, but they will most likely be for exclusive games and video playback only. I think the Xbox really loses out, in this scenario, as they have the worst exclusive game lineup, imho. I rarely buy games day one, so waiting for the PC port for a year long exclusive game isn't a big deal. The only thing that could change my mind is if the new achievements system is really engaging. Right now it seems as it will just be used as advertisement to get people to play your game, i.e. get 100 kills this weekend and get 100 gamer points. What I would like to see is a more organic achievement system. Say developers see 95% of people playing the game one way i.e. playing as a pyromancer in Dark Souls. They then can create achievements to start steering people to play using a different style that they had originally designed for but not many people actually used i.e. a faith build, thereby bringing new life into the game. Some would say that this is just bad game design but I feel it could be applied in a way that could keep the game fresh.
What I was really hoping from Microsoft was to include a CableCard reader in the device and then partner with Tivo or create their own DVR system. If the XBOX could eliminate the $15 a month I pay for renting my cable box, it would have been a day one purchase. I doubt the TV integration they showed will be that useful and snappy as they made it seem. The NFL partnership, also, seems gimicky.
I agree that the online requirement is not that big of a deal. Always online could have been a big problem based on server load, i.e. SimCity and Diablo III, server mainteance, or connection drops but the once per 24 hour limit should be easy to maintain for 99% of users. I'm pretty anti-used games/pro digital distribution, but I worry that the savings that the publishers will see from the lack of used games won't be shared with the consumer. I am expecting a pretty fluid pricing structure now for games, in which, a game that may orginally be released at $60 drops down to $15-$20 swiftly if it does not sell. I'm hoping publishers will now have the forsight and power to see that not all games are worth $60 and they should price their respective game where the demand dictates.
