See, there's the balance.
Pros:
1. Lucas' filthy stupidity will never touch the franchise again.
2. All of the terrible EU material is trashed.
3. No more Lucas.
4. J.J. Abrams, which means decent action-y bits.
Cons:
1. As above, even if Disney will do a better job than Lucas, that doesn't necessarily mean 'good'. Also:
2. Disney will never make another Empire.
3. J.J. Abrams, which means that canon will be reduced to a series of references to rope in the fanboys and plot will be mostly eclipsed by action.
4. This trailer is an eyesore. This trailer. This trailer. This trailer. This trailer. This trailer. This trailer. This trailer. This trailer. This trailer. This trailer. This trailer. This trailer.

Also, that lightsaber with lightsaber hilt is fucking stupid for one reason:
Know what happens when that hilt catches the blade of an enemy lightsaber? The bit that projects the crossguard gets cut off because it isn't flush with the hilt and lightsabers aren't lightsaber-proofed. So it's worse than useless because it inspires false confidence while also making it easier for the user to cut off bits of themself while twirling the thing around.
