the AF already has an alt art card.
The AF2A has an alt art card. Literally the least-used ship in the entire game, bar none. I see more Glad-II's than AF2A's. I can't remember the last time I saw one on the table.
Look at Apparent Rarity...
The Assault Frigate has one Alt Art Card (and one could argue it was done to encourage people to try to use them more often)
The Gladiator II now has an Alt Art Card (and one could argue as above as well...)
... Same as with the Nebulon-B Escort Card (which is popular as Yavaris, but less so as Salvation)
Granted, my argument falls apart with the Victory Alt Art Card, as I honestly don't know which one that is...
... The ISD-II for the Massing at Sullust Event was something different... Because out of everyone who got those cards, only a small fraction of those players actually Got the ISD to be able to use it immediately... it was more Commemerative than anything else - which is why it actually says the Massing of Sullust on the Card, rather than just being Plain Jane like the other Alt-Art Cards...
I figure they'll get to them eventually - Corvettes Included...
Then We'll start seeing Wave 3
This is true, and it was a running joke around here that FFG only released AA cards for ships nobody used.
But then people started using Yavaris, and GSD-II's, while there is still no reason ever to use the AF2A.
