Well not sure what we're arguing about, I agree with you that I hope the BC stuff can be removed.
It looks like MS has reserved up to 6GB for cache for X360 which is pretty good, it would be cool if they had a selectable cache size and # of directories, but it's not something I'm gonna get all excited about if its not there. I would rather have the space for game saves, downloads, demo's and expansion packs anyways.
I was just saying there's no reason they should need more than 2.5GB for BC. Should we be allowed to delete it is another topic, but I would say yes. The ideal solution is to use the X360's cache directories which has been promised to developers anyways.
As far as me being forgiving, but I'm far from forgiving. I have called MS out alot in the last 6 months. I must admit I backup all games to my HDD, so load times for me are about 1/3 the normal speed, with or without cache, though I haven't heard any complaints about it, most people are just happy to have a HDD in the first place.
