Ya saw that on steam yesterday. New they were lying a few months ago, when rumor hit saying there was a new one on way, and they said, no there is no plans for another.
Its I can wait to see the E3 reveal. Jus tot bad, when games are usually revealed there its least 6 months away
I have played every game in the series since it was first released. Just hope that maybe this time they might put in a co-op like every one asks for.
