Suggestion: New Armatars. There's some useful information about this subject located in that thread.
cormyn has stated in a thread that with the reputation system when a user gains enough they'll be able to upload their own Armatar to the site. I can't remember if he meant we had to draw it ourselves or if we could grab the picture off of the internet. With the grabbing it off the internet, they do have to worry about copyright laws. So, I think it's the draw it ourselves idea.
Also, they could have some new Armatars already and are just waiting until AG3 comes out to release them to the public. Well, that's just an idea that I have. Can't say for sure.
No. Why would they delete these current Armatars? Also if you hate them so much then why are you using one? I think all of these current ones are nice in their one way. I only like the animal ones. Well, that's off subject.
On subject, they should be rolling out new Armatars or letting us make and submit our own for ourselves. You never know what'll happen in AG3.
One idea we've had is that unlocking an achievement in a game will make the game icon available to you as an Armatar. So if you play a perfect Exit Path game or something, you'd get the Exit Path icon as your armatar.
Whether that's permanent or temporary, or we just make it available to you whenever you want it, we haven't decided. But that's one of several plans we have for Armatars.
