@chinnyreckon you might be right, though that thread is about a lot of things.
As you can see in my answer, i've tried to cover as much as i could.
EA got the right to develop new games, but the old games are retained for distribution by Disney. EA has no say in that and they can only do something about the games developed by themseleves (even the KOTOR 1, which was developed by Bioware, is published by Disney in collaboration with Aspyr, Aspyr handling the MAC and mobile releases of the series, as KOTOR was developed by Bioware for LucasArts and published by LucasArts)
So porting the old games is a no go for EA, unless Disney lets them do that. EA was allowed to continue to operate SWTOR, as Disney had no MMO on PC for SW. For how long that will still be possible, we will see.
Porting an old game means having access to the original code, having people that are at least familiar with the code (ideal would be to have on the payroll people that worked with that very code), having the production documents and so on. It's a LOT of work.
Gearbox remaster of Homeworld encountered a problem when they've discovered that the code for the Homeworld Cataclysm was lost. Beamdog met such a situation while trying to remaster Baldur's Gate 1 (some parts of the code where lost) and Icewind Dale 2 (hence, no Enhanced Edition for IWD2). Trouble with very old games is that sometimes companies lose things because a number of factors: lack of backups, poor storing conditions, lost production documents and so on. It might not be the case for the old SW Battlefront games, as Lucas was quite careful with certain things, but the people that were familiar with the code are long gone.
But, there is a but...EA has its third chance next year (with the launch of the final movie of the new trilogy). If they can manage to bring more of the features wanted by the fans in the final game, then we might have a Battlefront that could surpass the SW: Battlefront 2 from 2005.
There are quite a few nice things in SW: Battlefront 2 2017 and there are a few bad things, too. Not gonna mention the bad, as they were debated too many times. But there are some nice things done right. Plus, the game looks gorgeous. I don't know if the game can go from a 7 (my personal score) to a 8.5 and i actually doubt that they can save much at this point, but i do hope that the third one will learn from the 2015 and 2017 editions and will make the game that the fans want. EA has the resources to make a great game, the only thing they need is to assume some risks (something hard to do, as they are a public company and shareholders and investors are usually adverse to risk). If they can ignore for once what the people with the money want, they might actually be pleasantly surprised by their customers.
And yes, i would love a remaster of the SWBF 2005😉
