Let's talk voice actors!
Throughout the trailer, I recognized several of the voice actors by ear, but I barely know any of their names, and it's generally hard for me to place who else they've voiced. Can additional people help me on this?
The speaking characters in the 1 April trailer are:
Garon
Dancer Lady (singing, and likely the game titles)
Marx
Ryouma
Sakura
Hoshidan archer dude
These characters also spoke, but only single lines:
Queen of Hoshido ("yokatta")
Camilla ("daijoubu?")
Nohrian twintailed imouto ("onii-chan!")
Kazahana ("atarimae da yo!")
Tsubaki ("hai")
Orochi ("taihen ja!")
male Kamui ("son'na...")
I'll update this post upon further discoveries.
Updates:
Marx - Koyasu Takehito
Hoshidan archer - Kaji Yuuki
