I was watching the features video for the latest patch of Diablo 3, and it looks like Blizz is getting more heavily into rewarding fluff – portraits, pets, exclusive transmog gear or dyes, banners.
Then I remembered the cross-promotional stuff they’ve been doing for years, with pets and mounts – Hearthstone -> Heroes, Diablo -> WoW, Diablo -> Heroes, Heroes -> Hearthstone…
And then I remembered that they recently upped the ante by giving the Diablo hero away in HotS if you own a copy of D3.
So the logical next step, is for Blizzard to start having pets or card backs or portraits or other fluff attainable by completing tasks in other games. Defeat this rare in WoW to unlock a pet in D3. Reach max level in Hardcore D3 to get a HotS mount. Win X games in Hearthstone to earn some transmog item in WoW.
What do you think? Possible?
