I can't help but hope.
To get a bit more serious, it does strike me that Quackshot does fit quite nicely with New DuckTales; given how New DuckTales is integrating a ton of 90's Disney IP into a single universe, and has a much more adventurous Donald, it doesn't seem like a huge jump to tying them together.
However, if there *was* a game based on the New DuckTales IP on the way... I think it would probably have DuckTales in the title somewhere! DuckTales: Quackshots I could absolutely believe, but Quackshots alone? Fishy. I am wondering if there's a possibility that this is a Jarate/Yakuza RPG thing and a reveal disguised as an April Fools' joke.
Edit: Oh, wait, the hashtag threw me off, they are calling it DuckTales: Quackshots. That's one concern out of the way.
