Since the other post is getting too lengthy, I decided to make a new post about this.
Edgeline Tokyo made two articles about this event, and as well as my friend who went to the event gives a summary what the event was like.
Since there's going to be a bluray and DVD release. According to info on amazon:
Now also available to order on CDjapan 
Edgeline posted pic and comments from the guest performs in the show.
- Played the music of Butterfly
- Miyazaki singing Brave heart
- then some talking,
- Played the PV on the up-coming ending theme by Knife of Day "Boku ni totte." and also a brand new PV for Chapter 3.Our convo got abit messy so I'm confused what he meant by which PV. But he mentioned there was a scene with AtlurKabuterimon fighting Meicrackmon, and AtlurKabuterimon said he will not let Meicrackmon escaped. There was also a scene they show the lake where the bus is , seems like they are in the digital world.
(FYI: The lake and the special bus they spent the first night in digital world, where Garurumon evolved. Also the same bus that took them back to the Human World)
- Appmon commercial.
- The voice actors played a special mini-drama/skit, about them going to beach BBQ.
- Then concert:Beat Hit, Break up!, I wish
- An endless tale (As shown in the pic, they play the record of Wada's voice, and has a mic on the side beside her , as they are singing together)
- Then Miyazaki Ayumi and AiM sung all the Digimon Openings by Wada with the crowd : The Biggest Dreamer, Target ~ Akai Shougeki ~, Hirari, Fire!!.
- Remembrance of Mizutani-san by AiM
- Remembrance of Wada by Miyazaki and AiM
- Miyazaki and AiM singing Seven
- Remember Wada and Mizutani
- All staff are singing Butterfly with the crowd and concludes the event.
