Maybe 3 years in Human World = 10 or more years in Machine World? And remember that Gokaiger's year is not really clear, maybe it's far from 2011. I just hope the Timeranger tribute will mention what year is the present day in Gokaiger.
I remember reading somewhere on TV Tropes that the kid who stole the ShinkenRed key was Takeru's grandson. Yeah...:redface2: the youth of most of the Warriors, as well as most of them still being alive (I don't think even Akaranger, Big One, or any of Kenji Ohba's characters, would be alive if Takeru was old enough to have a grandchild), precludes Gokaiger taking too much time in the future.
Because Jan, Kaoru, Akashi, Shinkengers, Go-ongers, and all the other returnees look a lot older?
It cannot be too far away. It has to be two years or less. Which complete contradicts the first episode. "Years passed and Super Sentai faded into legend", yeah right.
In the TVN subs the years passed line is not present though..
Even so, the way it's phrased does seem to suggest a passage of time longer than... like, a couple months. I think it's just kind of a problem the series has, with wanting to feel like this generations-spanning epic, but having to deal with the fact that most of the actors they want to return aren't actually that much older.
