The Mass Effect Trilogy has been listed for a PlayStation 4 and Xbox One release by Chilean retailer Zmart. Bioware's quote on Twitter by Aaryn Flynn, GM for BioWare's Edmonton & Montreal studios, has suggested that this bundle is being released on next gen systems: "We have discussed that internally. If we can put solid plans together we'll share."
Furthermore, BioWare has admitted to "discussing" this idea of remastering the Mass Effect trilogy back in March. Hopefully, this release will not cut into development of the next entry in the Mass Effect series, that we will apparently be hearing more about later this year.
Among other things, BioWare also has a new IP in the works as well as an unannounced Star Wars game on their plates.
