I recently rented Killzone 2 to compare it to 3 (that is already out in Russia btw) and had a terrible experience with it. I was actually all for the weighty weapons on paper but 30 minutes into the game I found myself dying over and over during reload or changing weapons. The fact that you can only carry one gun was pretty bad too, especially during the later parts of the game. Cover straight up didn't work. And even though the story wasn't that important it didn't help that it was pretty boring.
 
I can't believe that all of these things were addressed in Killzone 3. Shooting is responsive and fun. Cover works as intended. Story is actually very entertaining and it takes you to all sorts of crazy places. The whole game just feels great. I breezed through it without stopping and had a great time. I haven't tried the multi-player yet but with all these improvements I'm sure it's great too.
P.S.
Virtual Malcolm Mcdowell is perfect.

Yeah from all the hours I have played in Killzone 2 (160 I think) Killzone 3 feels great but still has a certain weighty feel that makes the game unique.  
 
I really can't wait for this game, Killzone 2 is my favourite game this generation.

No complaints from me either. I played Killzone 2 and loved it, but welcome all of the new changes. The singleplayer demo was mint. Sliding to cover, and being able to move while in cover and pop in and out without having to hold down the L2 button is a huge relief. The faster more responsive and fluid controls and animations are welcome too. The melee kills are massively entertaining and give me a rush everytime I do one, be it on a human controller player or an npc, it's good stuff all around. All in all from the demo's and beta I feel Killzone 3 is a massive improvement and a great achievement for Guerrilla Games.

i had no problems with killzone 2 but this seems like a nice set of changes. 
 
hopefully resistance 3 can do the same for that series because 2 was kind of awful compared to the first.

" @Grissefar:   Completely disagree with you, I thought the open beta was fantastic, and the singleplayer demo seemed just fine. It's all about the multiplayer in Killzone, though. "

This.  The MP beta was so much fun, thanks in large part to the Move.  At some point the neighbors will knock to inquire about the satanic red orb floating around in the darkness. "

The beta has blown me away.  Playing with the move controller has reinvigorated my interest towards playing an fps on the console.
 
I was excited to finally play killzone 2 a few months ago when i got my ps3 and was complete and utterly underwhelmed, i probably plays about 2 hours of it, and it probably will be all i ever play of it.

I loved the demo so much compared to Killzone 2, I broke down and pre ordered.

While I enjoyed Killzone 2 well enough, I haven't really gone back to it after I played through the campaign. Considering that, while I knew I was going to buy Killzone 3, I thought I'd get it just as a time-passer until the games I really want get released. After playing the singleplayer demo, I can say that I'm actually pretty excited for the release of this game. Even more than Bulletstorm, surprisingly enough for me (that is in no way a slam on Bulletstorm, I'm pretty excited for that game too!)

I'm enjoying the changes to KZ3. I miss my boost pill, but some of the new ones are just too badass. But I liked at least having the option of switching perks between classes.

Wel KZ2 was fine. But not really spectacular. You dear Sir, need to buy Mass Effect 2. "
