Thanks so much for the help, everyone.
purpleparadox- I really appreciate your comparison to your own Samwise. It's great to know that there are other people as attached to literary heroes as I am.
Spider-Man- Thanks, you're right; I just needed a little push.
sologuy369- I like that plan. I intentionally left out Black Widow. I didn't know anything about her, and I had thought she was just a SHIELD Agent (I never really ventured from X Men). From looking her up on Wikipedia, I now know that she is indeed "super". Though if I was going to spend $70, I'd do it on Jean instead of the Quinjet set.
Hive & The Lego Dr.- You are definitely correct in saying that I would be regretful of my purchase if Jean was later released. I do think though that we will not see her again, however. There was no X Men related reveals for 2013 at SDCC among the numerous unveiled. There isn't anything really going on for the X Men right now that I think could bring Jean in. She's dead for one thing. I do know that a new Wolverine is coming out soon, but Jean isn't slated to appear. I think it would take a full X Men line to bring Jean out, and I don't foresee that happening.

Unfortunately, LEGO has taken on a new theme in which they only produce one female character per line (see DINO, Alien Conquest, Marvel Superheroes, NINJAGO first and second wave, Kingdoms second wave, Atlantis second wave) whom is only released in the largest set. That doesn't include any of the themes with currently no female characters or themes with a single female character that is reused or sold in a lower to mid range set. I don't want to rant about gender equality, but Jean probably won't happen unless a BIG X Men set (think the Mansion) is released in a full-fledged line the way things are currently. Unfortunately, LEGO sees Superheroes as a theme for boys. Thankfully, the X Team has always been gender and racially diverse, so there is hope for a more friendly line. I would love to see that happen. I'm fairly certain the Chopper set did well, so X Men sets will surely sell.
If Jean is released, I don't see the Phoenix happening but instead a more modern all black or black and yellow suit. The Phoenix is MY Jean Grey. Hell, I wear a silver necklace everyday of the Phoenix Force insignia.
I have decided I need this in my life. I'm a student, but I actually got a part time job two weeks ago that works around my Summer classes. I think this extra cash will help cover this. I have hardly spent on Lego this year, so I'll buy this and quit while I'm ahead. I may have to wait for the hype to die down a little on Ebay, but I will have my Child Of Light And Darkness. I might dip my toe a little into customization and make her a Dark Phoenix or White Phoenix of the Crown costume as well.
TL;DR: I'm going to make this fig mine. I'll make a post here when I have my hands on her.
