Sony Europe boss David Reeves says the company hasn't ruled out introducing a hard disk drive to PlayStation Portable despite the upcoming launch of PSP Slim and Lite.
"I think that it certainly is not ruled out," Reeves told Eurogamer in an interview published today.
"The only thing I would say is that the flash memory is simply so cheap - you can get an 8GB Memory Stick for under 100 Euros, and on 8GB you can get a lot of content."
"I think the big debate is - there's a point in time when you have to put a stake in the ground and say we're going to go with flash memory or we're going to go with hard drive. I don't think they've put that stake in the ground just yet," he added.
"So they're thinking about it - I think they'll get through Christmas and think about what the next step would be. You might hear more later."
Reeves also said that Sony's decision to launch service-based products for PSP at Leipzig - including satellite navigation and video-on-demand - won't stop the company investing in games software, which it's aware it needs to do.
What's more, Reeves echoed comments made at E3 that he expects some of it to come via PlayStation Network, like Calling All Cars. Asked if he sees PSN as a potential feeder service to PSP, and vice versa, he said: "Yeah, it will be."
"On PSN you get an instant reaction - 'Calling All Cars, great game, okay, can I have it on PSP?' Okay, why not?"
