Expect a Mass Effect announcement - and not necessarily Mass Effect 3 announcement - at the Spike Video Game Awards early next month. There's a Bioware teaser after the break and I assure you that it is Mass Effect...
How do I know? Check this Bioware tweet here as it reveals a barcode. Scanning the barcode gives me a tin of baked beans. After that, check the video below closely. There are subliminal flashes of a tin of baked beans. You can check other sites theories here and here, then come back to mine. I know a tin of baked beans has nothing to do with Mass Effect but I am still working on the theory.
