No I think they're gonna head straight for the sequel era - it's more profitable that way.
Also, 2000-2010 had an over saturation of prequel products. So I don't think people want more of that any time soon
Ugh- I hate it but you're probably right. My working assumption was that they'd try and make their Battlefront 2 as feature complete as the original BF2, but I bet they use the inclusion of Ep 7 as an excuse to avoid doing prequel stuff. And if they don't do prequel that seems like a very big task to add in via DLC (pretty much the equivalent of BC2 Vietnam DLC in scale).
