Basically the way I see this is:

If July 14th Update = Final last update before the Summer 2017 Event update, then Saratoga Kai Ni is highly possible.

If however there is another update in-between July 14th and the Summer 2017 Event update, there is the possiblity Saratoga Kai Ni update is included there instead of the 14th Update.

The fact is that Devs did not announce Saratoga's Kai Ni remodel hint via Twitter yet (They only did this via Comptiq and Zuiun Event), so there is the possibility that this will be a total surprise update, or they have it planned for another update in-between July 14th and Summer event update.
