Koller: PlayStation Move number one reason to purchase PS3

SCEA's John Koller has said PlayStation Move is the number one reason for people to purchase a PS3 for the rest of this year.

In an interview published on Gamespot, Koller says in studies carried out by Sony, the motion controller came out on top for reasons to purchase PS3.

You can watch the eleven minute interview below, in which Koller explains the new device, and how Sony's hoping it'll enable people to get off their couch and be more engaged with its games, something he says has never been done properly until now.

PlayStation Move launches on September 17 in the UK, followed by a US release on September 19.
