Ok, let's me try again - it's pretty clear when you play it but somehow I find it very hard to write it down:
The Dragon Knight Saga has been approached as if it were an entire new game from the point of view of the core item-fever & hack and slash parts of the gameplay as well as getting rid of those areas that we considered to be "boring" in Ego Draconis. We've upgraded the engine, upgrade the graphics, upgraded the audio, changed the levels, changed the balancing, modified several features and where possible applied those changes to both Ego Draconis and Flames Of Vengeance. Additionally, on the 360, we changed almost the entire interface, modified the levels and gameplay to increase performance, changed the camera system/controls, and made sure the 360 has its a different balancing than the PC version as both platforms play differently. If on PC it plays more "streamlined", on 360 it's almost as if it's a different (and better) game.
Since its a pretty big redesign of several parts of Ego Draconis, it's impossible to convert Ego Draconis in The Dragon Knight Saga with just a patch - for that there are too many changes - but those areas of the game that we can change, without affecting the existing savegames, we've tried to change through the upcoming patch. For instance, if you install FOV, you get a better-looking Ego Draconis, and also the engine improvements. A patch which would bring ED to DKS would consist of replacing almost every single file, and it's guarnateed that you wouldn't be able to play any of your previous saves.
So D2:ED + FoV (which includes patch) does not equal DKS, but it's as close as we can get it without destroying the save-games.
For people who don't buy FOV, we'll provide a D2:ED patch, but I need to add that it's up to the various publishers to release it.
The intended audience of DKS consists primarily of people who didn't buy D2:ED, but in the same breath I have to say that I think that all the changes done make the entire experience more fun and I wished we could've launched DKS as ED.
I hope you can still follow and this makes sense to you
