Birth was also double rider'd with Proto Birth appearing so I can see that being hinted if not subtly at least.

Hazard forms look epic, I'm curious about how they'll work with the Bottle Change gimmick figures. It would be cool to have swapable eyes to represent different Best Matches being used, but my guess is that we'll just get the RabbitTank version that may or may not be compatible with others in the line.

I love Rogue's design, the colors are gorgeous and the suit's look is a nice mix of regal and menacing. The Nebula Gun is okay, the colors are a little gaudy especially combined with the sword, but I'm sure they'll grow on me.

I don't like the Kaiser Bros designs. At all. Those gears just look bulky, heavy and generally unwieldy, with the normal forms looking especially unbalanced. Plus, simply mirroring the design is kind of lazy, I know it's because they're brothers but I wish there was something to make the Engine one look engine-y and the Remocon one look remote-control-y. The combining thing is cool in theory, but in practice it just looks like an uglier version of what Patoranger is going to do.

Kamen Rider Build UniRaser Form:

"Unicorn! Keshigomu! Best Match! Are You Ready? Ikkaki Shoukyou! UniRaser! Yeay!"

According to CraneJoe, ScorpionGold is cancelled

As a main release. It’s still one of the thirty Best Matches so it will have to be released eventually.

TurtleWatch Best Match

Seems like this best match has Time Travel abilities... which could be a problem for Build's story although the writing has been top notch so far so if anyone could do time travel well then it might be this one.

Please no. Time travel is such a hard thing to get right. If Build's able to slow down or stop time with it that'd be better

TurtleWatch must have the ability to control time: freeze, pause, rewind & fast-forward. Even based on a turtle, slowdown time.

Turtle probably gives him pretty good defensive capabilities while Watch likely speeds up time so he's not slowed down by the turtle half. Fast defensive form would work well.
