I would bet money on that. I am not am emu dev myself, nor am I an expert at reverse engineering game consoles, but the progress that Cemu is making is blazing. Even for hacky HLE. Cemu is running circles around it's open source alternative. If they really cared about moving WiiU emulation forward, they could at least release the source code and not let others contribute. It's not like the emulation community is competing for money here ...right?
Who knows. Maybe the Cemu team will wait for more information to surface, maybe for some better documentation from the reverse engineering community, or some leaked documents from other sources. Then open up their code and play it off like it was always a level playing field.
