I would like a Vong Event

I'm not interested in the Vong myself. While a lot of people enjoy the EU, you'll probably find that a majority of Star Wars fans either don't care about it, or flat out don't like anything too far out of cannon. Plus, it's been already said that the next trilogy will not be anything like the books, thus pushing the Vong story line further out to the fringe of the Star Wars mythos.

ok i did a little work on what is cannon and not:

""In July 2001, Lucas gave his opinion on the matter of what is canon in Star Wars during an interview with Cinescape magazine:

Snip.

Also the new movies are a direct violation to what lucas wants

There are different levels of canon:

As you've heard in the first KOTOR game, Canderous Ordo encountered a Yuuzhan Vong Yorik-et ship:

So a possible appearance by the Vong in SWTOR I wouldn't rule out. Of course not a huge invasion but maybe a small group of them in some form or one of their creatures. Also it's possible for Zonama Sekot to make an appearance and if the oppertunity was there to make it explorable, I wouldn't say no. It's possible maybe the beast in Terror from Beyond is a Vong creature but that's only speculation.

""In July 2001, Lucas gave his opinion on the matter of what is canon in Star Wars during an interview with Cinescape magazine:

"There are two worlds here," explained Lucas. "There's my world, which is the movies, and there's this other world that has been created, which I say is the parallel universe—the licensing world of the books, games and comic books. They don't intrude on my world, which is a select period of time, [but] they do intrude in between the movies. I don't get too involved in the parallel universe." ""
AND

LUCAS: "I've left pretty explicit instructions for there not to be any more features. There will definitely be no Episodes VII-IX. That's because there isn't any story. I mean, I never thought of anything. And now there have been novels about the events after Episode VI, which isn't at all what I would have done with it. The Star Wars story is really the tragedy of Darth Vader. That is the story. Once Vader dies, he doesn't come back to life, the Emperor doesn't get cloned and Luke doesn't get married...

so he only has the movies and prequels he doesnt care about the games or the books. in the C-Cannon the books and games will correlate, so that means if you've read the books where Canderous became the new Mandalore from the Revan Book that means that his Madnos did fight the Coral Skipper and not knowing it could have an spot in the Old Republic history, So we COULD have a Vong event just not called the Vong, They could be called the ExoGalactic invaders for all I care.

Also the new movies are a direct violation to what lucas wants

I would, cause even IF it made a cameo, it wouldn't be explorable by us as it doesn't get settled on until 89 BBY and it is unlikely that that creature is related to the Vong. Could it be a Creature from the same Galaxy that the Vong came from, sure but that would probably be the only similarity it had to the Vong.
