clues, what was not in the force awakens teaser trailer .....I didn't see any Jedi

As I watched the trailer. I saw the obvious points that were sure to causesome chatter in the forums.
After watching the trailer probably a dozen times on my big screen. I started paying attention to what was not shown.
for example.
no jedi in jedi robes were shown.
boyega, ridley, and presumably driver as grave robber...though the latter is pure speculation but speculated by many.
not seeing Gleeson or Pip (the parkour kid) it leads me to believe that showing them in their wardrobe could be a sign that whom ever they are their wardrobe would give away significant info.
I am of the thought that atleast Gleeson is a Jedi and only wears jedi robes. Perhaps the ssame is true for Pip.
The main point of my theory is they don't want to spoil the who is who yet so they won't show certain characters until the film is released.
I am thinking we will get a glimpse of the big three in the next trailer as seeing them won't give away too much.
I can thinkof a few more clues not shown Iin the trailer but I think it wouldbe fun to hear others ideas on this.
To be clear this is to speculate on the characters not shown and if the reason is because if shown we would know what kind of characters they may be playing.
As stated above my pic on this Is Gleeson is a jedi in jedi robes
