I'd love to have an expansion game or full sequel. Due to how the game ended, I do think there's opportunities for Naughty Dog to expand on the series. However, if they did frequent entries like what Capcom does with Resident Evil, I fear they would gradually go downhill because of how quickly they could push them out. Naughty Dog are known for their exceptional quality. Capcom are able to offer greatness here and there. Don't count them out as a whole if they mess up here and there, because they can deliver. But sometimes, they get way too money hungry for their own good.
