I was thinking the same question as you, since I'm on the crossroads to choosing a new console. It might be possible if there is a way to link both Sony and Microsoft accounts on your Bungie.net profile, but if nobody can do that, then i don't think there is a way. If the exclusive emblem ends up being a downloadable thing, you could always try moving it onto your PS4, but it all depends if the file is 'Microsoft Only'. I wish you luck when the time comes!

Poking around on the site, there is a way to link both to your Sony and Microsoft accounts to your Bungie.net profile, so it looks like it may be possible. I'm guessing the emblem is stored on your account so when you log in with a connected account on either console, it'll unlock. Hopefully someone can confirm!

I thought I had read somewhere on the forums that it was one or the other. I was under the impression that the emblem would be on your actual character then an emblem on your profile .
