Some things are not compatible like skins. With regards to other content, I'm pretty sure people will figure out a way to get them over. We all still trying to find out what can and cannot be made compatible in a way that is usable.

I said this in another thread, but I'll repeat it here as well -- I'm actually pretty confident someone will build a bridge for skins, because they always do. Yeah, I know. I'm replying to Zev0, who knows more about this than almost anyone. My money's still on the table saying a conversion tool will get made. People are amazingly clever and no one's ready to give up their Sabby-skin collection.
