the helix didn't look to good on that video. it'd be an awesome ride if they would of brought it out to the lake again, there's so much useless unused room in that area, they really should of produced more of a ride after the MCBR.
Also the trains, it technically takes up no more space then an Intamin hyper, 2 seats a train, 2 cars a row, just another new take on it and experiment basically. im sure it'll be better then being in the back row of a car with two people immediately infront of you.
