Oh kindly shove the "realism? in MY fantasy movie?!" nonsense somewhere uncomfortable; as people have spent countless hours on countless forums explaining to "judgement reservers" the world over; "realism" and "internal consistency" are not the same thing. It doesn't matter if a fictional world follows the rules of reality as long as it follows its own already-established rules. Yes, moronic crap like the "lightwhip" exist in the EU, but given Disney literally eradicated the entire EU from canon just a short while ago specifically so they could pick out the good bits and ignore the nonsensical drivel that naturally builds up in a semi-official ecosystem that often amounted to legitimised fanfics(a great decision IMO; the EU had many, many more stinkers than it had gems, particularly in the post-RotJ stuff that the films will now be overwriting), their existence is hardly a good peg for anyone to hang a positive view of the broadsword on.
Your unnecessary rudeness aside, pray tell what "established" rules does the core crop of films have that precludes the inclusion of a light-saber with a hand-guard?
Because I heard the same bullshit when Episode One came out and self-proclaimed "die-hard fans" bitched about Darth Maul's dual-sword. They cried, "Myah! That's not canon! You couldn't wield that properly!"
Now I see the same people saying dual-bladed light-sabers are fine, but this hand-guard thing.... IT'S BLASPHEMY!
So please, do enlighten me as to why the sword in the teaser is somehow 'offensive' to the canon of the core films "established rules". Rules, it seems, that are so fluid as to not even matter.
[edit]
Or perhaps I should say: Rules so fluid that the only real stipulation be, "it's a sword that glows".
[edit 2]
For that matter, how dare you scream about "internal consistency". Even the films aren't consistent with the displayed behavior and physical properties of light-sabers.
