Yoshida has played The Last Guardian, but with what controller?

In what seemed like an obvious set up during the PlayStation 4 All Access broadcast last night, host Geoff Keighley asked Sony's Shuhei Yoshida whether he had played The Last Guardian. The answer was yes, but Yoshida said he could not remember which controller he used (DualShock 3 or DualShock 4) when asked by Keighley. It should be noted that there likely wasn't a single second of the broadcast that wasn't approved by Sony (the interview with Yoshida and Boyes was recorded) - so it doesn't take a genius to figure that Sony wants to keep the game in the news.
