Interesting. I always thought that a Crystal VC release would happen eventually, but had no idea about when. Feels like it wasn't that long since the G/S release happened, it was almost 3 months ago but feels like yesterday to me. Though I didn't get either of them so maybe that's one of the reasons why.
Anyway, will I get this? Maybe. G/S was a definite no for me, but Crystal is a big maybe. Why is it a maybe and not a definite no when the Johto games are my least favorites in the series? Well, there are a few reasons. First of all, Crystal is my favorite Johto game, I had more fun with it than I had with both G/S and HG/SS. I like how it tried to address some of the issues G/S had with the Pokemon placement and distribution. The battery of my Crystal copy died many years ago, making me unable to play it anymore. That said, I probably wouldn't have played it even if I could, but being able to occasionally go back and visit my old memories would have been fun. There are also a couple of things I wanted to do in my original Crystal copy which I never got around to. Two major things stand out. The first is catching the legendaries. Or essentially Raikou, Entei and Ho-Oh at least, since I got Suicune and Lugia in my original game. The second is to complete the Battle Tower. It is to date the only battle facility in any generation that I have never even won 7 battles in a row at, so being able to finally do that would be fun. Finally, Crystal is also the only game to feature Kris as a playable character. I prefer her over Ethan and Lyra so it would be fun to play as her again.
The Celebi thing is also interesting since I never got a Celebi in the original Gen 2 games. I didn't get a Celebi at all until Gen 4 thanks to Wi-Fi trading. I hope it will be available in-game without an event for all regions.
Unfortunately, not everthing is sparkling about Crystal. I will probably miss being able to use the Mareep line, maybe some of the other version exclusives too. I will also miss having access to Lugia's and Ho-Oh's signature moves, Gen 2 Aeroblast was always so damn cool to watch in the games. Then I'm not sure if I can handle the massive Johto gameplay flaws combined with badly aged game mechanics, physics and graphics either.
So, in the end, I'm not saying I will get the game. Nor am I saying I won't. It is not a yes or no, but a maybe. I will have to see. Right now I don't have time either, I have been so busy with real life for the past months that it feels like I have barely had time for anything. I haven't even completed the main story in Ultra Moon even if I got the game on the release date, and I am still quite far from completing it. Though this doesn't really affect Crystal as it is still more than a month from now until it gets released (it is released one day before my birthday!). If I get it, it will probably not be on or close to the release date. I happened to come across the prices for G/S on the eShop today while downloading the patch for Ultra Moon, and I saw that they were actually quite cheap (though they are probably more expansive in my country than in most others). If Crystal gets the same price then it will be fine, money-wise.
Okay, enough rambling from my side. I just wanted to write this now that I could.
TL;DR: Maybe.
