I asked if the amount of emblems etc I already have will be transformed into an "equal" amount of dilithium or if they will reset it all.
...gonna have to file this in the "oddly specific" category...
But how about this - the devs intend to replace your emblems, merits, etc. with a quantity of dilithium that, as near as they can determine, is roughly equal in value to what they're replacing, once they figure out the conversion rate. Which they haven't figured out yet. It probably won't be numerically equal, since dilithium is going to be more finely graded than the currency it's replacing.
I don't have a linkable source on this, but I got this from the STOked live stream where they broadcast an interview with a dev on the subject of dilithium. If it's not in tomorrow's release, it should be out within a couple of weeks.
