I know someone who will be very happy to hear they're adapting the FMP novels into this.
Gundam X is a personal favorite for me. Other returning works are nice but I guess E7 fans will be disappointed. Surprised it took so long for Diebuster to make it into one of these.
Honestly I didn't like E7AO or AGE but I think they'd do fine in Super Robot Wars. It's not like Banpresto themselves are good at anything other than hot blood.
AGE will probably only ever include the Second Gen stuff since its the part of the show that sucked the least (and didn't turn into a massive clusterfuck of Shamaylan-esque twists and rampant stupidity like 3rd Gen did; even Sunrise likes to pretend that particular part didn't exist).
AO will be entertaining just to see how they'd handle the Retcon Gun.
Knowing Gundam X was one of the first to be confirmed as returning made my heart leap for Joy. It's my second favorite full Gundam series after the original.
Even if Gundam X wasn't a full series. :v
Another thing I forgot to be disappoint in was the lack of Gundam ZZ or Hartaway's Flash. Especially when Z1 went and hung that Chekhov's Gun for all to see. Also no Gravion or Original Dancouga for a Final Obari Special (to go with the Final Inazuma Special *crosses fingers*).
But otherwise, I'm not too disappointed in the current roster. This will at least avoid the massive clusterfuck that was Alpha 3's roster additions. Plus, Gargantua means one more for the Stoic Veteran Band of Brothers (though I highly suspect that Gargantua will be handled by having the FMP class take a field trip to Waterworld).
