I took the liberty of summarizing all of the info Color809 leaked on Baidu today

What we know so far:
-Gotchard’s belt is orange, the center of the belt has a display screen, very similar to the concept belt shown off during the transformation exhibition, but with handles on both sides
-Their gimmick is cards, they use a barcode system ala decade and decker. Swipe two cards to transform, the card combination for the base form is locust + steam train. The cards have a kind of rarity system.
-Gotchard’s base form is blue, with goggles on his forehead and a white scarf around their neck. His eyes resemble two arrows facing each other
-It would seem that Gotchard primarily has a nautical motif, with that being the most prominent design element in his suit, with the motifs from his gimmicks (locust and steam train) being more minor
-Alongside Gotchard, there seems to be two other riders from the start

One of them better be a female.

So the gimmick will be cards? What kind? Trading cards? Playing cards? Credit/Debit cards? Keycards?

Color described them as heavily resembling the Decade and Decker cards, barcodes in all, not really sure how what kind of cards those would be considered. Trading Cards I guess would be the closest since they have different rarity

Considering the nautical theme being the major influence on the costume, I'm guessing that different Riders will be more likely to have different henshin devices this season.

Like what?

• Henshin Belt?
• Henshin Brace?
• Henshin Grip?
• Henshin Sheath?
• Henshin Wand?
• Henshin Mask?

Just going by White Knight Chronicles

Given cards are the collectibles, I'm expecting at least one to look like a cross between a Duel Disk from Yu-Gi-Oh and the circular controls where cards are placed on the arcade machine Datas is based on.

According to Color (the leaker), this sketch is the closest to what Gotchard actually looks like so far, particularly in how the eyes look

The other Chinese leaker (in the same vein as color) drew what the eyes look like. Worth noting that unlike the last post they have actually seen the suit. Looks like the eyes have a kind of gradient on them

Eyes kind of remind me of Zi-O.

The nautical theme is cool, especially since it hasn't been used since... X. I mean just as the main one, not separate forms like OOO or Snipe. If it also shifts the action to the port, giving us some new locations would be generally wonderful. On the other hand, recalling last year's mistakes, he is most likely not a sailor, but a traffic controller.
But I don't really like the transformation mechanism. Geats also uses two items, and two fusing cards are so Ultraman-like that it smacks of plagiarism. Although, I must admit, the locust and the steam locomotive have not yet been used, but they go well together.
