My guess is fully playable before the end of the year. Wouldn't say 100% bug-free but my bet is something pretty close to that.
Yeah agree. Nintendo managed to shut-down Yuzu because the devs where asking for money, but as long as the devs of this emulator don't do anything that retarded, Sony won't be able to do a thing.
Not only that, but the guys from Yuzu were greedy cunts. They openly discussed piracy in their discord, they bragged about the money they were getting from Patreon donations (which is a grey area because while emulators aren't illegal, profiting from them is), but the worst thing they did was provide decryption keys for games to donors. TOTK for instance was playable on emulators before its official release date. This probably sealed their fate.
Even still, the repository was copied and a lot of different teams made forks of the emulators, so we'll still see Yuzu in some form with future emulators anyway. Nintendo only killed the main branch, they didn't kill Switch emulation because that's effectively impossible. Even if Sony successfully takes down ShadPS4, someone else will take over and continue the project.
Gaffers are clueless thinking this can be stopped.
