What sets do you think will be in the Expanded format and Standard format come september? Here are my predictions.
Standard: FFI-FOC
Expanded: XY-FOC
Standard: FFI-FOC
Expanded: XY-FOC
Remember that VS seeker got a reprint in Ancient Origins as a secret rare. So we have that for standard stillPresuming that thought is put into rotation, I think that standard going to ROS on would make a lot of sense. It would shake up the meta pretty massively with PHF leaving, but would keep Shaymin EX in play, which would maintain quite a lot of the games speed on setup. Seems like that would make for a very healthy meta.

There are so many things wrong here. The 2014 Worlds format was NXD-on. For 2015, it BCR-(The first BW2 set) on. XY era is technically from XY-present (I think). All of the sets do start with XY. Did you forget about ORAS in the last two games? In fact, none of your stuff about the last 2 mainstream games work. Last year, there were 3. Also, PRC-on would be the last 1 game. Also, the rotation always happens after Worlds, with one exception (2010-2011 season). Furthermore, you say leave Expanded as is. Then you use regionals as a guidelines of when to rotate Standard, and regionals are Expanded only events, so it makes no sense for you to make a correlation there.I think the next rotation will be Primal Clash onwards. TCG 2014 used all of the BW-era cards, and Worlds of TCG 2015 allowed Plasma Storm onwards.
The releases for Black/White 2 and Plasma Storm were roughly a month apart if we go by release dates in Japan, so let's operate under the assumption that Plasma Storm marked the introduction of Black/White 2. If we go by this, the cards that were allowed for Worlds 2015 were cards that were released during the Black/White 2 games (Plasma Storm to Legendary Treasures) and the XY era (XY Base to Flashfire). Pokemon X/Y and Pokemon Black/White 2 were the last 2 games to be released at the time, so if we operate under the assumption that Standard will only consist of cards released during the time span of the last 2 mainstream Pokemon games, the oldest set allowed in Standard next year will be Primal Clash, since that set marked the beginning of the Omega Ruby/Alpha Sapphire games. As an aside, if I had to guess what Expanded will be like, I would say that it will only consist of cards from the last 2 generations of the mainstream series (BW' 5th gen and XY's 6th gen at this moment).
Fall Regionals for the 2016-'17 season will probably just be Expanded like it is right now, but once we get to Winter or Spring Regionals and the Sun/Moon generation gets a few sets, we'll have to work with PC-onwards as the Standard format.
One also should be careful about trying to predict the rotation. To give you an idea:
Obviously I did not list promo cards or miniature sets.

While other circumstances matter, this does suggest things can vary quite a bit. As few as no sets is possible, as many as seven is not unprecedented. The average is a little under four, with four being the middle value as well, and most common is three sets.
