Their counterparts in the Celestials moved around a bit, changed color and animal (Azure to Jade, Tiger from West to North, Tortoise to Ox, etc), but the connection is there.
However, there is sometimes a fifth Guardian Beast that joins those four: Huang Long, the Yellow Dragon.
Now, I'm not saying its a hint, but it is kind of curious, wouldn't you say?
