I'm going to address this point-by-point.
#1 Profit. If EA/Bioware were to release the original trilogy for next gen, it would be an easy 60 to 80 bucks per sale on something that the company doesn't have to spend another dime adding content to, or creating advertising or packaging for. Plus with the multiplayer aspect of ME3 a chance to generate even more revenue with the micro transactions for that is simple. Pure profit.
It wouldn't be "pure profit." The devs would have to rework the game to run on the new console's system architecture. I too am no programmer, but I am aware that it would take a small team to accomplish this in a timely manner. The devs would also need to optimize all three games to run smoother and cleaner (i.e. improving graphics, textures, and loadtimes). As for marketing, it may not require as much work, but it would still require enough to make consumers aware of this project. They would also need to set up new multiplayer servers for the Xbox One and PS4. Not exactly expensive, but not nearly "pure profit."
#2 Game Saves. A lot of people have asked questions about how their game saves would be effected by things like platform upgrade/swap. A digital download version of the trilogy fixes this issue with relative ease. Plus it means a thing like a genesis type DLC would be unnecessary and (tying into article #1) create more profit ie. 60-80 dollars for the trilogy vs. 15-20 for a DLC. Or make both and "Reap" the profit either way. Regardless the company and the fans both win.
The Dragon Age Keep will likely be a precursor for whatever manner they use to import saves for the next Mass Effect. Not everyone is going to buy a next gen port of the trilogy, so resources will go into making new Mass Effect Genesis regardless. That being said, it would make things easier for a straight-up save import to the next game. The profits from a next-gen port could be utilized to fund both either way, so yes, both the company and fans would win.
#3 Quality of current offerings. With the release of the new consoles a short time ago, it is painful to see that games like "Pure Chess" are what developers are fronting as the next generation of exciting new gameplay. And yes I know that most of the release cycle will start getting good after E3, but I would rather play old games on a new console then some of the tripe we seem to be getting shoveled.
I could not agree more. Now would be a prime time to take advantage of the rather bland market of next gen games. The Mass Effect Trilogy would provide not only high quality single experience, but a fun and exciting multiplayer experience as well. It would also provide an opportunity to add more multiplayer content.
