There's surely enough stuff between free radicals attempt, that other developer and now even slant sixs bits of a new battlefront for another dev team to gather it all together, polish and release within two years... you could probably start from scratch if you rereleased BF2 as an HD arcade release - with dlc of the missing BF1 maps like 'Rhen Var', Bespin, err, I forget the others. Then you use the millions of pounds you just made in 1 hour of release to fund Battlefront 3 for next gen.
Or, for free, ring me up and sign me up as the new star wars game idea man, Metal Gear Force, Star Wars Solid, Star Wars of the old republic (oh hang on), Far Jedi, Grand Theft Tauntaun, Minemilleniumfalcon, XCOM Enemy is quite known it's clearly the sith and many more!
It's all in the game...
