We're just so used to hearing about the next console in a sequence, it's a shock to hear the word "if."

While many still assume Sony will eventually produce a PlayStation 5, the company isn't ready to talk about it. In fact, they're not even willing to say they'll make a fifth home console.

Game Informer's Lorne Lanning revealed he had a private dinner with Sony boss Shuhei Yoshida during this year's DICE event (as cited by Attack Of The Fanboy ) and the following exchange took place:

"I said, ‘What does the PlayStation 5 look like?’ And he said, ‘You mean if…’ And I was like, ‘Whoa. Are you willing to say that on stage?’ And he said, ‘Yeah, it’s an if.'"

We keep hearing about the updated PS4 and Xbox One consoles (the latest report said Sony's upgraded machine will be significantly more powerful ), so maybe Sony and Microsoft believe the new units will keep going for a while. And don't forget that lots of experts and analysts think this is the final generation of consoles, that the industry will ultimately want to give consumers a universal machine that plays all games (like any movie player plays all movies).

Could PS4 be the last PlayStation console? If so, what do you expect to see in the future?
