Bioware recently made comments on some post-launch features they are planning on introducing in the game.
I found the article on Kotaku Australia, so I figured I should post it beacuse "who checks Kotaku Australia?"

Some cool things that they plan on adding:
Guild Banks
Guild Capital Ships
UI Customization
New Warzones
Expanded Space gameplay
More Legacy options

Guild Capital Ships

^ This. So much win. Some kinda in-game guild HQ is great and I could not think of better one for a Star Wars theme. Shame you can't invite people to your own ship, though.

I think a Roll system should be moved to the top of the list.

The guild capital ship feature seems pretty cool.
I'm interested to see how everything else will turn out as well.

I am so for the Capital Ship and I am wondering what they mean by expanded Space gameplay...maybe not so linear path battles?

I want an MMO version of X-Wing Alliance. Anything less will still be disappointing.

This is amazing. I want it all. And a roll feature, like Fluttershy said. Less headaches that way. xD

A Capital Ship? For the Guild? I want one immediately.

I'll jump on it first and start naming names:

HMS Radiant Dawn

HMS Solar Wind

HMS Moonsailer

HMS Rising Sun

HMS Friendship

We also need more rainbows on the hull. Those alone will increase our heat diffusion systems to 120% of their standard operating capacity.
