Will we see these PS3 titles in this generation?

[Rainbird]

I think those five games are going to happen this generation, with probably Starhawk being the least likely one to come out.

But I think it's fine, Sony create sequels to good games on top of lots of new IPs. The only game on your list that isn't new IP from this generation is Killzone (provided Starhawk isn't actually directly related to Warhawk).
