Heroes of the Storm launches today! Alas, without Gnome representation. :(
Blizz has cross-promotional awards with HotS, WoW, and Hearthstone:
- Grave Golem pet for WoW for level 20 in HotS, Dire Wolf Mount for HotS for level 100 in WoW (http://us.battle.net/heroes/en/blog/19508174/world-of-warcraft-and-heroes-of-the-storm-rewards-6-2-2015)
- Heroes-themed Card Back for Hearthstone for level 12 in HotS, Hearthstone Card Mount in HotS for winning 100 matches in Hearthstone’s Play Mode (http://us.battle.net/heroes/en/blog/19529839/hearthstone-and-heroes-of-the-storm-rewards-6-2-2015)
Also, Blizz had previewed, back in March, a cool Mechanospider mount, which it turns out is available for unlocking now for free! Unfortunately, it requires some sort of Facebook shenanigans. I've never felt I was popular enough to have, nor need, a social network, but I suppose I'll endeavor to jump through the hoops, since the mount is pretty cool, and should make a nifty Gnome mount. 8) Information is at http://teambuilder.heroesofthestorm.com/

Edit: There is an option for inclusion of video from YouTube, but it didn't seem to work for me, so just inserted the link. However, with checking the BB Code info (http://help.shivtr.com/customer/portal/articles/381334-bbcode) and persistence, got it to work.
