I definitely agree with you there. This is how Disney operates (they are always like "show us the major money NOW", and like I said, we are in a new era. Throw out most of the rules that "used to be" when Lucas was in control, because they are releasing pretty much a film a year. Over the next year and a half, we will be bombarded with sets. I suspect, we will see a dozen new sets before the Force Friday event in September, then we will see 5 or 6 sets for Rogue One. Then, we will see the typical January release with 5 or 6 more sets, then another 5 to 7 for Ep 8… All before May 2017. Disney/lego isn't making this to pad reseller/investor wallets, they are out for their own.
I very much see the new x-wing replacing this one. I also see many of these sets having about 9 month release cycles, and there could be a lot of replacements, a lot of rehashes, a lot of minor updates with just small changes in sets.
Like I said in a previous thread. I was planning on giving my son the black x-wing until I saw the new variation and that changed my tune. Now, i'll buy both, and invest in both, but he's only getting one. I'll wait to see which one is more common, before I make that decision. But i'm not going to give him both, just because of the change in color and 1 minifig change. But, this is just the start of what I suspect will be a headspinning amount of sets that will be similar to one another. The rehashes will become redundant, nothing will be safe from a rehash, and expect them often.
