I don't quite think so...
with PS2, it's also easy. ICO (while not a blockbuster bringing up PS2 will often bring up comments regarding ICO), God of War, Ratchet and Clank, etc...
Now if I go up to some random bloke on the street and say oi, have you seen the cool games on PS3, what titles would they immediately connect to the system? Resistance 1 probably. Other than that. Not much. And that's a problem. It's easy for the hardcore consoler's to pull up a list of awesome games, and most of those games deserve the recognition.
But the general public, not so much. Especially once the advertising blitz dies down. Killzone 2 for example.
That's where I think PS3 is failing with regards to having a killer App.

Ico is hugely popular on internet message boards (and so is it's spiritual successor Shadow of the Colossus), but I doubt your average bloke on the streets ever heard of either of the two.
PS2 was assotiated with MGS2, FFX, GTA, GT and (albeit much later) God of War and probably Singstar (amongst the casual gamer crowd that is)
Except for MGS4 (which sold very well I believe and is pretty much what the system is associated with as of now) all of the above are either multiplatform now or have yet to be released.
I don't think the software situation has really changed all that much: the games that sold well on the PS2 continue to sell well on the PS3. Some of them are multi platfrom now (like GTA) so a big chunk of the sails are now obviously on the 360's side.
None of the more hardcore oriented PS2 games besides God of War and Gran Turismo ever sold in Halo or Gears of War kinda numbers, at least not right out of the gate. The Jak games were million sellers, but they weren't multi million sellers (the first game is now), same with the Ratchet games. Uncharted is now at 2.5 million units, the latest Ratchet is at 1.5, MGS4 sold more than 4 million units.
That's all more or less in line with the sales back on the PS2.
New IPs like Motorstorm and LBP sold resepectable numbers as well. Certainly better than some of Sony's last gen experiments like Primal or Ghosthunter.
I'm pretty sure FFXIII will do great as well and so will Gran Turismo (Prologue sold close to 3 million copies, and that's a glorified demo for crying out loud), God of War and most likely Uncharted 2.
On the other hand Halo was always insanely popular (and I know quite a few folks who bought their 360 just because of that one game) and Gears really came out at the perfect time: it got rave reviews, it looked better than everything else on consoles (including Resistance obviously), it was the complete package (campaign, co-op, multiplayer) and it was insanely violent which I believe resonated extremely well with console's audience.
At the time the PS3 was pretty much a laughing stock, with the E3 2K5 trailers mocking it at every turn, further bogged down by a 600 dollar price tag and and barely a game to show for it. (didn't Time Magazine call the PS3 something like the biggest hardware failure of the new millenium?)
Another 360 1st party game with damn good sales was Fable II, but that's pretty much where the big success story ends already.
Most of the multiplatform sales juggernauts do very well on both systems after all. (GTAIV, CoDIV and World at War, Assassin's Creed)
