Given what we've seen from EN 1 and 2, why do you even WANT EN 3? On the offchance they are any promising, they will still have the likes of Mori and Kronii whispering in their ears. Maybe they'll see how Gura and Ina can go long periods without streaming and still rake in the cash. My point is, even if Cover somehow magically found great girls they didn't find the first 2 times they held auditions, the current ENs, their senpais, will poison them.
