well its no secret that some bungie employees really wanted the "SPACE TIGER" to make it in the game, but should it be??? I actually really want the tiger to make an appearance in the game. it doesn't necessarily have to be a "space tiger" but I think it would be cool if the main leader of the guardians (if there is one) had like the last tiger in existence and it was like white with black stripes. or even just a Easter egg and if you kill it you get a special weapon called "eye of the tiger" or something funny like that.
Anyway.... something to think about. leave your thoughts in the comments
I could see the space tiger being more of a decoration item for a home or tent as depicted in the concept art. I'd imagine if anything they will be present in NPC cut scenes and mission story lines to add to the ambience of the local.
