Sony may be preparing to release the PlayStation 4 tomorrow – but it’s also plotting an announcement or two as part of a massive Spike TV broadcast. We already know that we’ll be getting a glimpse of The Last of Us’ first single player add-on, as well as a peak behind the curtains at the platform holder’s newest research and development lab – but the firm’s also got another reveal plotted that not even Worldwide Studios president Shuhei Yoshida can believe.

True, this strikes us as typical Geoff Keighley hype building, but the video that the GameTrailers TV host posted on Instagram is pretty funny. “Even [Shuhei Yoshida] was surprised by one announcement yesterday during a taping for PS4 All Access,” the Canadian journalist Tweeted. Realistically, what it could be? We're not sure, but we don’t recommend putting your hype levels into overdrive just yet, as at least then there’s a chance that you’ll still be pleasantly surprised.

Incidentally, fellow teaser Hideo Kojima has been hinting at an announcement during tomorrow night’s broadcast, too. “There'll be a shocking PS4 related announcement that will blow your mind,” he told followers earlier this afternoon. Feel free to send your best guesses on the back of a postcard. Or, y’know, it might be quicker to use the comments section below. Technology, huh?
