There have been several posts by Bioware developers on Twitter this morning (my time) that look very interesting.
Lead gameplay designer Christina Norman tweeted: "I am celebrating 2011 by playing a Mass Effect game that will probably be released in 2011."
Jesse Houston, another Bioware developer (@gtez), then asked Norman "@truffle me2 ps3?"
Norman replied to questions: "I am not talking about me2 ps3! Good guess, but no."
Finally, Houston answered: "@truffle hehe"
This points to (yet another) Mass Effect game for this year. Woohoo?
