This publish actually made my day. You can not believe just how so much time I had spent for this information!
Thank you!

I think you are onto something… I think I see Juniper walking around @ 1:02-1:09. it looks like she is wearing pink clothing, and she is approaching the main character’s home…

Wonder if the receiving was cut out so we can speculate if Juniper is there. If she is, that’s a pretty important tidbit, so it’s understandable for it to be cut.

It says “Can also be played on the 3DS!”. But it means as in ‘fully functional on the 3DS!’.

There are 2 main things cut in vid. The narrative flow breaks hence we know.
1.When the rival and little sister talk to the protagonist. The rival says he will go with you to receive your first Pokémon but why/who is entirely cut out.
2.When the exclamation mark appears. Someone must have been waiting there but it skips straight to the selection screen.

If not, my guess goes to the Trainer School.

Ooh, looks like the Musketeer trio is getting plot significance in game? .o.
