I understand it's cool to hate the prequels but seriously, I love episodes 1 and 3. 2 had the worst problems. Sure Jar Jar sucked, but the rest of it was awesome. (Pod Racing, Darth Maul. Qui Gon Jinn is my all time favorite prequel character and one of my all time favorite characters besides Han/Chewi. Obi-Wan is so badass in the prequels,)
The EU is essentially Star Wars fan fiction which retcons all kinds of things that needed no explanation (Darth Vader's Glove being a mandalorian iron gauntlet with an ancient sith amulet. We all saw Darth block the blaster and were just like, wow, Darth V is a badass.) or cause force users too seem absolutely absurd (Dorsk 81 pushing SEVENTEEN STAR DESTROYERS out of the system). So yeah, Episode 1 didn't need to talk about midichlorians, but at least it was GL doing it, and not some random writer.
So while I think it would be cool to see some more ships coming, no matter where they were from. I would hope that the black suns were only on the Imperial Side with some sweet Star Vipers, Shadows of The Empire Style.
