I put it to you, that your expectations are too low, you're too used to the way other games developers have done things because they didn't know how to do it.
David Braben had seamless planetary landings in FE2 AND FFE (basically the same game) in 1993 and that fit on a 1.44MB floppy disk ... 1.44MB consider that for a moment.
Here we are in the age of modern gaming where games can be multiples of GB in size, the CQC update yesterday was 6GB, for an update!!!
And you honestly think, knowing the core die-hard Elite fans, like myself, demand nothing less than being able to manually fly our craft down to a planet's surface like we could in FE2 ... that Frontier would risk the rage in the community by making it a CUT SCENE. I think not.
