What's the bidding that someone or something is gonna cameo from WarCraft III? I've no idea what, but, as you recall, there was a Hydralisk in WC III, and a Night Elf dancer hologram for a bar....I doubt Blizz is gonna leave it at that though.
at least one orc, that's a given imo night elves too of course other than that I wouldn't be surprised to see figures like arthas or Illidan, maybe some demon from Burning Legion? though maybe not Legion since it's the other way around - fel stalker reminds me of some zergling concepts: http://www.sonsofthestorm.com/viewer.php?artist=samwise&cat=warcraft&art=129
There's prolly going to be a bonus level where you're one of the characters from WC3 and you take on SC2 units.
I think we may run into Wirt's 4th(?) leg. i think there has been one in Diablo 2, one in Warcraft 3 and one in WoW. there is also a wirt's leg in Hellgate: London.
It was for the Merc Haven where Reapers came from: [img width=250 height=200]http://www.starcraftlive.net/scl/images/merchaven01.jpg[/img] As for WC things in SC, I don't mind it as long as they stay in the map editor and come nowhere near melee maps or campaign levels.
I wouldn't mind seeing game-crossovers i think its kinda nice when you suddenly realinse when your base is being demolished you have a Night Elf strip dancer on top of your reapers Merc Haven. and they are starin up her skirt while eatin a big mac... and be blown to pieces.
I'm still expecting a secret mission where we get to play as Nova. That and minor hero with a name like Tyreal or Arthas.
Artanis: This is not Warcraft in space! It's much more sophistica- Orc: get these ugly things away from me! *running from zerglings* Artanis: Hmmm...well, I stand corrected, but we are 3-D this time!
