From what I've seen over the horizon so to speak, (hur hur) there does appear to be a lot of good stuff coming. It is an exciting time for ED, if it all turns out to be true.
To me personally we don't know enough to judge. I have tried the base building / stamping engine in frontiers other games, and if they're planning on selling them in the store as we know it will likely be some form of the stamping ability rather than piece by piece building.. While im looking forward to space legs, im not sure about bases because i can't imagine a need for them at all in the game and they will be redundant with carriers for many things? Will be interesting to see what they come up with anyway.. if its not completely new stuff the bar will be immensely high.
