I remember hoping a re-release of 10188 with updated minifigures existed two years ago. You know, to have a more current, a go-between version, before the "real upgraded Death Star" would arrive at some point. I wondered why Lego hadn't done that, but concluded that they won't because a genuinely new Death Star would be needed so soon anyway. But now it's 2016, and if what CM4Sci said was accurate, then this is just a re-release of 10188 with updated minifigures, and not a new Death Star at all. Having gotten over the initial disappoinment, this makes me chuckle a bit, because I really didn't expect TLG to do a re-release at this point anymore. But maybe they can afford to play it safe, moneywise. It's not the 90s, and they are the second largest toy company in the world.
I feel slightly stupid. Like a kid, I waited for a "new" DS for over a year, and then it's precisely the re-release I would have liked existed in 2014. Well, I got my expectations wrong.
Also, just a guess, but perhaps Lego would have liked to do the re-release a couple of years ago, but decided to wait, because there was a new movie about the Death Star coming in just two years? Meaning Rogue One. Marketing, marketing.
