From DE's FAQ on cross-save/account-merging/account-linking etc - https://www.warframe.com/news/cross-platform-save
I was hoping so much to finally get this elusive frog skins when cross-save was announced...
If you were like me (on PC), who was looking for a potential chance to finally get access to Sony/Playstation exclusive Obsidian skins, then you're out of luck. Not going to happen. (And Vice Versa for Sony/Playstation users wanting the skins from other platforms). Sad, the only skin I cared about, and it had to be locked because Sony.
Nothing else to say, I'm just disappointed is all.
(I'm not so sure about the in case of account linking? But I'm assuming it's the same situation?)
