That is a good point. I hadn't stopped and thought about that.

Something tells me these Roidmudes will probably appear in the crossover movie.

People were worried about this, but I actually don't think Chase will come back in the final episode despite being in the preview for 48. After watching it a couple more times, it seems to me like the shots of the three Riders could very well be a flashback. Perhaps Shin is reflecting on his time as a Kamen Rider and having trouble thinking passed it. The shot where he fires his gun, mirroring his global freeze mistake, makes me think this episode will be all about Shinnosuke getting back on his feet as a normal kickass detective and moving on from his superhero days.

Until the next crossover movie of course. :p

Maybe Chase is a ghost in the final episode. I mean it's possible.

To me it looks much more like this will either be an AU story or will take place before the final episode. After what happened in the finale I cant really imagine this happening afterwards.

I'm just saying, look how much Shin is featured using his gun in the preview video and pictures. He's also not wearing the shift brace aside from that one shot with the three Riders.

I think the whole 3 riders together is probably going to be like what Gaim did in it's final episode, where the beginning is some undisclosed time in the past, in this case, before the final battle with Banno. Maybe sometime between episode 42 and 43, since we had that big gap from 30 to 23 Roidmudes.
Then the rest is post episode 47, as Shin doesn't have his Shift brace and the Chief is in his new uniform at the end.

My thoughts exactly.

Listing for a Drive Saga Kamen Rider Chaser Blu-Ray showed up. Looks like Drive might get a Gaiden or rather W-Returns treatment.
