The engine's been built. Most of the hard work for Killzone 3 has already been done in Killzone 2. So some tweaking, improving and adding extra content is all they'll need to do for number 3. Probably could take them only 2 years and with what they've said it looks like there's more room for them to spread around in the beefy ps3.
Killzone 2 is well prepared to becoming a good 5 million seller over the next 2 to 3 months as long as sony don't screw it up by not advertising it enough. Lots of european countries get left out of sony's marketing circle. They forget that europe is where they make most of their profit.
But what that matters most is that next month I will be playing Killzone 2, oblivious to any financial fame or failure that might be happening behind the scenes :D
