This is a biggie.
I am personally hoping that all firearms and other assorted toys convertover sweetly as well. Because otherwise it makes an awful lot of things obso.
Characters would be fairly easy depending on your take on time as it were.
Either way its gonna be a while before I get used to a new system.
If chars aren't compatible what do you plan on doing?
I will just rebuild the ones I need and replace the ones I don't.
Either way I will make it work.
