At the moment, the available X-Wing avatars just cover waves 1 and 2.
Since those releases, we've now seen:
- Wave 3 (B-Wing, HWK-290, Imperial Shuttle, TIE Bomber)
- Imperial aces (Royal Guard TIE Interceptor)
- Wave 4 (E-Wing, Z-95, TIE Defender, TIE Phantom)
- Rebel Medium Transport (with new X-Wing pilots)
- Rebel CR-90 Corvette
All those new ships! All that new ART! And none of it available as a forum avatar...
