If we have tokens saved up and then 4.3 hits and we haven't spent them before it hits, will the tokens get deleted? I know they reset honor points at new seasons and I forget about JPs and VPs.
I recently copied over my main again to the PTR - VP were made to JP and the surplus JP you get were made to gold. Same for CP and HP - but JC tokens were untouched so I'd say it's safe to say they remain unaffected.
I can't imagine they would be reset, although we have no official confirmation of this - it would cause a LOT of rage, and it wasn't done when epic gems were added with tokens in WotLK.
Honor points won't be reset at the new season; all conquest will be converted to honor points and you can go over the cap. However, if you are over the cap of 4000 on patch day, anything over the cap will be converted to silver, and the gold mailed to you.
