It just means that the Formidine Rift is in space, not on a planet. Any player of E: D 1.x can find the Formidine Rift, that way it is accessible even to the three people who play on Macs ;D
There are many clues/story to the Formidine Rift mystery being added to the game, some may require E: D 2.x to find, but whilst the clues are helpful to find the Formidine Rift, they are not necessary.
At least, that's my understanding :)
