Would not hold my breath for SFC4 as that would require alot of time/money to invest to create it.
But what it does mean is that utilities that the designers have can be modified for general use and supplied to the gaming community. That in itself is a major improvement, for the games that we all liked the most, the SFC1-2 OP ones. One of the major draw backs to the game was the lack of being able to change a UI for the OP and less games. With that addition alone will bring a huge boost, ability to make mods with new ships, to the games that will add life. I can not tell you how many modders wanted that ability, in fact that was so requested it actually made it into sfc 3, because it would add so much customization in a mod.
EAW and OP were the games that have kept most of us around and have never stopped being played. Add SFC 1 to that list as well if that utillity gets created.
