How long will rpcs3 take to finish or get to next step?

There's literally no one who can tell you. People work on it in their free time, this is not some software project where there's employees to give you a rough estimate, we could literally have a break for months with no progress.

I would really like a rule in the forum that an ETA question are disallowed, they contribute nothing and only lead to baseless speculation. While some might find that entertaining, I do not.
