Firstly, source of this info? I have never seen it.
Its how the lore carries on between 1.23 and 2.0 it only makes sense to see Dalamud blowing Gridania up in the opening cut scene, and I don't think they should let anyone miss Gridania getting blown up :D
I can see it now, perhaps an automatic timed cut scene just before servers go down for 2.0 maint (re-watchable for all legacy members after 2.0) with Dalamud getting near, and what ever it will do happens, then a message "To be continued at the launch of version 2.0) ahhh cliffhangers, you know you all love em.
