Small question about weapon evolution over 45

[Afshin]

Hi all

 

I currently have a true siren weapon+all other awakened siren. I have heard that upgrade paths will change with this new release. Here I have 2 questions:

1-Is this new path only for weapon or others gears will be affected too?

2-Am I mistaken by upgrading my weapon now that new path is going to be released? Will new path costs more than current one? Should I try to upgrade my weapon even more before release? or upgrading after release costs less ad will be better?

 

regards
