I think people seem to have forgotten how big the gap was between 1.0 and 2.0.

1.0 was switched off 12 November 2012
2.0 started up on 27 August 2013

There were some brief beta periods where you could play (including beta 4 where any changes you made carried over to the full 2.0 game), but it was essentially 9 months without the game running.

Not 9 months without content, 9 months of no game at all.

Square Enix certainly aren't going to want to shutdown again and I doubt the majority of the players would want them to either.

Sure we all want more flexibility with things, but it's not like they don't give us updates, we're just very demanding and always want more.
