^Yea but I don't put too much faith in Korean concept art, it changes all the time. Look at the gyro swing that Children's Park had on it's art and was still removed during the remodel. The concept art you posted was when it was a 2016 project themed to an alpine village before it became the 2018 project and themed to Fantasy Realms so it could still be the teal track if the plans were altered (although the Sheikra picture makes me hopeful it hasn't been.) I'm just glad to see any big coaster since it will be 10 years since T Express at Everland by the time it opens.
A lot of concept arts or signs are put up and left or is just a placeholder before things get confirmed even when plans change or get abandoned. Eagle's Fortress had a under refurbishment sign for years after it closed down and even now that site is covered with pictures of a grand hotel for Spring 2017 when the land is still just a flattened dirt pile. Very rarely does the art turn out anywhere near the final version.
Heck, I've got so used to smaller rides coming to Korea that, although this new update with a picture of Sheikra put those fears a little more to rest for me, with the construction site empty for so long, coupled with the news of a Zamperla Thunderbolt coming to Korea apparently around 2018, and the press release focusing more on "a 90 degree drop", I really thought that it might be what ended up here instead. Trust me, no-one wants to see a big B&M here more than me, and I would much prefer it over a Thunderbolt, but I've learnt that you really have to wait until track or the ride is on site here to know what the final version is. Heck even that original art showed a Mondial Ultra Max before they settled on the Zamperla model.
