There is a few new promos that have been revealed. The first one is the pinatas. It is thought that it will come Monday 20th. There will be 21 pinatas. #19 contains a Greyfell and #21 Shiny Yellow.
The maximum you can reach without passes (but finishing all objectives and clicks) is more likely to be #18. If you've done everything, you'll need around 10-15 passes (for HoPs). If you have not clicked as much as you could or didn't complete all objectives, you will probably use between 20 and 30 passes (HoPS) depending on how far you reached. One tip for using your passes. Wait until the very last days of the promo or if stuck with a hard pinata. You are more likely to get click bonuses at the end because you have a hard pinata or because it is the end and a bonus is added in the HoPs.
Objectives (click on English translation) -> http://thefutureoftomorrow.fr/article.php?id=144
Update on pinatas: it seems like without any pass but with all objectives and clicks (day & night), you can only reach #12 or #13, which would be really bad, because in this case, the number of pass to spend is at least twice as big as what I said before. This is only a speculation from a few players so don't start to panic But we'll have to check that :/

The second and third are a Maze and a Flower fight. It is not known which one will follow the pinatas. Most of the players say that the maze comes first since it was revealed before the Flower Fight, but according to the screenshots, the Flower Fight ends sooner than the Maze which lets me think that the Flower Battle comes first.

The Flower Fight is UFOs changed in Flowers and you can find gifts, but I think everyone knows that a Fight is
The first prize of the Fight is a Greyfell, and then prizes are offered to players until the 30,000th best players during the Fight.

The other promo is a Maze. If you find the exit, you will have Lovely Blue. You will have to explore a maze. Its map is covered by clouds and each time you make a move, you will discover more of the map. Gifts, candies and binoculars are placed in the maze (explained later). To explore the map you will take a horse to go with you. Each move takes 20% of energy (even though it sounds that it will be your horse's energy, it will actually be your own, which means that you cannot have more energy by switching your horse with another), and the regain is between 2 and 5% of energy/hour. This means that you need to wait four hours (min) to earn 20% energy back and discover another part of the maze. How to get 5% back each hour? Your horse has to have higher than a 4600GP total (for Howrse it may be a little less).
Candies are found in the maze are allows you to move without energy (one move/candy). Binoculars ( as I translated them) are also found in the maze are allows you to discover 10 cases of the map, BUT you CANNOT move. You are only allowed to see. You need either energy or a candy to move.
Gifts are gifts, found in the maze too.
Each move makes you discover a case of the map. The map is apparently a 22x22 one, or 484 cases.

List of the gifts: Whip, Bells, 1000e, x500 oat, Classical Saddle 2*, Shower, Philotes' Stroke, Croesus' Pactole, GA, Helios Ray, Titan's Challenge, Apocalypse's Seal, Fertility Wand, Hera's Pack, lunge, one Percheron Horse, 20x leather (totally forgot the translation. What we get from cows), Western saddle clothe 2*, x50 carrots, Hestia's Gift, Medusa's Blood, Zeus' Lightning, 6000e, the BMI that allows you to personalize your horse's name, Water trough, Classical bride 2*, Classical Saddle Clothe 2*, 10 aging points.
Lovey Blue is given to you when you find the EXIT of the map. It is NOT a gift found within the maze.

According to these information, the maze will bring the new draft horse AND Lovely Blue. I think that this also means that the maze will appear in May, probably by the middle/end of may. Second evidence to show that the Flower fight will be before the Maze.
Some pictures:




Update of the maze's map from the equideow preprod.

Enjoy!

The Wild horses. I started talking about them because it is believed that they will come back at some points. I'll keep looking for more information on Equideow.
Apparently, new unicorns will appear. Even though there is a pic kind of showing that information, there is no confirmation.
Winter and Summer will probably be in the reserved sales at some point during April. The date is not known yet, but keep an eye open on this side

If an objective number is marked with an * (ex. Win 25* competitions) - it means that the number needed differs from player to player based on different factors (number of horses, equus amount, etc.
