The PlayStation 4 is a hit. While there are no official figures from Sony about holiday sales, early reports have the console selling 2-to-1 over competitor Xbox One. And with the buzz of a new console launch out of the way, that means it's time to start focusing on what's next.

When MTV News caught up with PlayStation Software Product Development Head Scott Rohde at the launch event for the PS4, he was already mulling plans. And though we nudged and prompted him just a bit, there is one classic PS1 game he'd like to bring back for the new generation, if he had his druthers.

"One of my favorite games of all time is a game called 'PaRappa The Rapper,' " Rohde said. "It was one the first -- it might have been the first -- music rhythm game I can remember. Just the most memorable set of characters. If I have anything to say about it, I'd love to see someone like PaRappa make a new appearance on the PS4."

But the forward thinking talk didn't stop with games. Though we're only a month down the road from the launch of the PlayStation 4, Rohde and company already have their calendars tentatively marked for the PlayStation 5.

"We tend to start thinking about the development of the next system, surprisingly only a few years into the life cycle of the current gen," Rohde noted. The reasoning isn't just commerce, but also that creating a new console is the work of hundreds, if not thousands of people all over the world.

"As you can imagine there are hundreds of engineers, and partnerships around the globe that have to take place," Rohde continued. For the PlayStation 4, he added that there was, "lots of questioning that we did with the entire development community to make sure we were building [a] machine that everyone loved, to enable all those great lines in the creative community out there to build all kinds of great stuff."

Presumably, that's the same sort of conversations Rohde et al would like to have about the PS5. With several years until Sony starts tackling the PS5 in earnest, though, there's no clear idea on how the next console will shape up, or vary from the PS4. Instead, the focus is squarely on improving the current system.

"As soon as you launch a new console you have to take a breather, there's gonna be a couple of years where we're just enhancing this machine and making it as great as it can be," Rohde said. "And of course very soon, we'll start thinking about what we'll do next. That's the culture at Sony. We always have to do something that's bigger and better than what's already been done."

The PlayStation 4 is now available in stores everywhere. That is, if you can find one.
