He is right. While the PS3 has excellent titles, there is still no "I can't believe you didn't buy yet a PS3 to play this" title.
Microsoft has only one of those - "Halo". Master Chief is a culture icon. It got the original xbox into the market and was the primary reason for the xbox purchasing decision. Even two years after the release of the third installment you still have million of on-line users each night shooting, beating and blowing each other. People will still talk about Halo at water coolers. The title has huge legs and is selling consistently week in and week out.
The PS3 is still in search of a title that can create a similar cult-like reaction from the gamers. Something that can attract millions and will be replayable for years. It has great games, but all of them are either shooting stars with fast sales for a few weeks and then darkness (MGS4 in the USA for example) or has long legs but very small audiance (e.g. LBP).
