Update: The sharp eyes of commenter Arth Vader picked up that the gun in the pic is either the M-29 Incisor Sniper Rifle from the Mass Effect 2 Aegis Pack DLC or a reused asset. If it is the M-29, it would imply the game will be Mass Effect related.
Update 2: Recall that EA said last February that something "far-reaching" was coming to Mass Effect during the fourth quarter of the publisher's current fiscal year -- or in layman's terms: January 1 March 31, 2011.
Update 3: Okay, now things are just getting nerdy. BioWare blasted out the adjacent QR code on Twitter which, when decoded, spits out a string of 1s and 0s. When you convert this binary code (we told you: nerdy), it reads: 55.845. Of course, as everyone knows, 55.845 is the atomic mass of iron. Maybe the presence of the word "mass" in our findings isn't quite enough to go on, but we're sure you'll agree that the presence of the word "mass" coupled with a piece of fan fiction titled Mass Effect: Iron Rebirth is practically a smoking M-29 Incisor Sniper Rifle.
Update 4: And another QR code has been loosed upon the unsuspecting people of Twitter. This one is again some binary that translates into: 128.5°F. Converted to Celsius, that becomes -89.16666666666667°C. "The coldest temperature ever recorded on earth is -89.2 degrees Celsius (-128.5 degrees Fahrenheit) at Vostok, Antarctica on July 21, 1983," says Wikipedia; and this Mass Effect wiki page describes the Vostok solar system as "a medium system with four planets and an asteroid belt," itself named after the Soviet "Vostok Program" that resulted in the first manned space flight. Oh, and that asteroid belt that was mentioned? The wiki page calls it a "metal-rich asteroid." You know what else is metal? That's right, iron!
