Yep, looking forward to the stream. Maybe the upgrade path will have something to do with what they hinted about regarding old legendary gear (being able to sacrifice it for same-slot item growth). Maybe you have to sacrifice 100 legendary rocket launchers to evolve Gjallarhorn into Gjallarhorn II , for example. Knowing Bungie, they would then count that as a "new" exotic, so when they say TK has as many exotics as vanilla, it's actually just new versions of all the same guns, with a handful of brand new exotics thrown in (I sure hope that isn't the case!)
