What will be the first Six Flags park with a giga coaster?

Six Flags is known for their thrilling roller coasters, though we haven't seen any giga coaster (a complete circuit 300' - 399' tall coaster) being built at any Six Flags park. Though, I doubt that fact will live much longer, as I expect at least one Six Flags park to receive one in a few years, but which one? Here are some candidates of Six Flags parks capable of having a giga coaster:

Six Flags Over Texas
It's easy to start with the first Six Flags park, which opened in 1961. SFOT's last major investment was Titan in 2001 and I see the park getting something big in a few years. A giga coaster would work well as the park encompasses the whole Dallas-Fort Worth area with no direct competition from any amusement park. Six Flags corporate likes to say that SFOT is their flagship park, so why not build their first giga coaster there? The park has enough room as the abandoned shopping center could be a possible location for one.

Six Flags Great Adventure
This park is the East Coast's biggest amusement park with Kingda Ka, a record breaking coaster, and El Toro, voted the #1 wooden coaster, so I would not be surprised if they received a giga coaster in a few years. The last time SFGAdv had a major investment was back in 2006, El Toro, so they are overdue for a major investment. The park basically has unlimited land with over 3 square miles of land, mostly untouched by man.

Six Flags Magic Mountain
Known as the world's most thrilling park, Magic Mountain is the park with the most roller coasters and in 1997 - 2003, there was seven consecutive years of new coasters. Though, Magic Mountain recently has gotten smaller, more frequent investments. Full Throttle, Green Lantern, Lex Luthor, and Apocalypse don't count as major investments for this park in my book. I count Tatsu, back in 2006, as the last really major investment. You could say that Full Throttle is a major investment, so I'd not heavily disagree that Magic Mountain's most recent major investment is opening next month. Anyways, the park has tons of land which can easily occupy a giga coaster.

Six Flags Great America
One of Six Flags' most popular parks and one of the enthusiast favorite Six Flags parks, Great America is Chicago's massive amusement park. Chicagoland has no amusement park that comes any close to SFGAm. The last major investment is 2012, X-Flight. Though, being one of Six Flags' most attended amusement parks, I would not be surprised if they got another massive investment in a few years. The problem is that if a new attraction is over 125', it needs to be approved by Gurnee. It would be difficult to build such a massive coaster, though the park already has a 285' Intamin gyro tower, Sky Trek Tower, and a B&M hyper coaster.

These are the potential candidates for the first Six Flags park to have a giga coaster. What are your thoughts? Comment below.
