So LBP2 in Jan, Killzone 3 in Feb/March, Infamous 2 in spring, Resistance 3 in Sept, Uncharted 3 in November
Motorstorm 3 at some point.
not bad at all
do these fit in with your acceptable windows for follow ups as per Mass Effect ? 
Sure

I said in the ME thread that I find 2 year dev cycles to be the standard this gen. My worry with ME is that it's more like 1.5 years if you take account of the ME2 DLC. Plus there's just an expectation that rpgs should have longer dev periods because they are bigger games with more content than say a linear FPS.
That being said, Killzone 3 always seemed a bit too soon considering the long gap between KZ1 -> KZ2. Infamous 2 is taking their sweet 3 year time, Resistance 3 skipped a year to "give it more care" and is getting a 3 year dev cycle instead of 2.

for me :
who cares
as long as the levels don't suck balls
who cares
who cares
and
OH HELL YES
in that order
For me:
sequel to the best game on ps3, very excited
who cares, looks shit
omg yes, Infamous was a lot of fun
wait and see
can't wait, naughty dog games rock
and for motorstorm 3: looking forward to it, PR was fun and I like city racing with paths that change like split/second (hopefully with less bullshit AI this time)
