The CG and lack of W worries are pretty unfounded right now.

As stated, CG in anime has only gotten better over time. If they use any CG for this, and that alone is also an assumption and not really confirmed considering we literally have no footage showing otherwise, I highly doubt it'll look bad.

As for the lack of W in-suit, I could care less. I enjoy Kamen Rider for more than just the monster fights. Following Shotarou and Philip on more in-depth mysteries and character arcs that pick up beyond the series is what I'm most interested in. W and Accel appearing is obvious, but having the promotions being very out-of-suit focused is pretty smart cause these characters are WHY we like these masked heroes in the first place.
