Optimus Prime semi-trailer in the very first mission.

Haha, yeah, I noticed it, too, I even took a screenshot of it!

Any word on Secret Missions? I know destroying the Science Station nets you one but I dont know about any others.

That's about it I think.
BTW! On the secret mission (Castanar), in the room where you kill the Brutalisk, there is a vat on the right part of the room that has a Metroid in it!

EDIT: There's also one slightly to left of that one that also contains a Metroid, and one on the leftmost part of the room that has a Tauren marine in it.

Chris Metzen is a reporter for half a second on the UNN broadcast where Mengsk holds a press conference (he isn't at the press conference)

(Unconfirmed, but pretty sure)

Tychus when he is in the Odin can say: "It's time to kick ass and chew bubble gum".

On the secret level, at the part when you can get reinforcements, if you outside outside the landing area up the right wall, you'll see Grunty the Murloc Marine flipping on an asteroid. You can't reach him though so there's no "secret found" message.

[GRUNT]

Apparently, I am a Murloc.

Can I see it? I missed that.
