They'd make more money leaving it as is and just having it up for download as a classic, why bother with all the R and D costs. Its a niche title anyway and the recent failure of the latest to do that well is going to go on a pie chart in the shareholders meetings to show a downward trend regarding the IP or that type of game rather then the quality of the product being taken into account in terms of sales.
His story is over and that would be stupid bringing him back.
I wish they introduced Shepard in the new mass effect
It would be very nice but I highly doubt it as would of already happened or we would of already heard about it by now if this was going to happen so no I don't believe we will see a remastered version of the games
They'd probably farm it out to the lowest bidder and you'd end up with a lackluster effort like the recent Arkham or Bioshock collections. Could be awesome if they got a great dev house like Bluepoint involved, but I just can't see that happening...
