In terms of innovation and new IP's it's why I bought my PS3 in the first place. As a publisher they seem to take risks, and are always probing for new and exciting games.
As for the milking issue, I agree to a limited extent. While I'm excited for almost all of Sony's first party outings this year, I will be dissapointed if Killzone 4 or Uncharted 4 are then announced next year. At the moment though, I can't point to a single franchise that's really being milked by Sony in light of other publishers releases. Beyond perhaps R&C, but that seems to be a consistent million seller no matter how many of them they release, so the fanbase obviously exists and Sony supplies them, there's also the issue of it probably being a nice cash cow for Insomniac, who as independants could use the relaible source of income without throwing the dice at a new IP.
So I'm happy with Sony now, they've established some great new IP's this gen and are expanding on them, but I hope there's still room for some more exciting new IP's, and they won't just stick to playing it safe.
