I've dedicated pretty much my whole week speculating about the M2's library had it released as a game console, and along with the spreadsheet, here's some additional notes...

• A 1996 issue of REAL Magazine made very clear that Trouble Decker (the dolphin demo) was only meant as a tech demo, but I'm not sure if tech demos would've counted towards "in-development titles" or not.
• 3DO Magazine Japan - June 1996: Panasonic Wondertainment head Takeshi Matsuo confirms the existence of "table games" on M2, along with the usual arcade/action stuff
• Edge - October 1996: Wondertainment software producer Hiroyuki Sakai confirms two internal games in development based off the prerendered demos from E3 1995, a racing game and a first-person shooter. He does not mention Studio 3DO once.
• London Gazette - March 1997: Omcourt Limited (t/a Perceptions) liquidated on the 28th of February that year.
• EGM - May 1997: confirms the existence of an M2 update to Tokimeki Memorial, along with a soccer game (Heat of Eleven) and a new racing IP. Also rumours of a Street Fighter III port and sequel to Strider.
• Ultra Game Players - July 1997: A former 3DO employee confirms ASCII, Enix, Hudson, Treasure and Namco as M2 licensees.
• NextGen - August 1997: Boss Game Studios and Iguana are confirmed US developers. Boss' Top Gear Rally from later that year lists Panasonic Wondertainment head Takeshi Matsuo under Special Thanks.
• Edge - January 1998: the M2 was shown at Digitalmedia World Expo in November 1997, and showcased three games (Trouble Decker, a scrolling shoot-em-up called Memory Breaker and Digital Dance Mix).
• Genki was long rumoured to be making a shooter similar to Panzer Dragoon. Considering a Sega game was there to show off the tech, third parties definitely weren't off the table. The Jan-Feb and Mar-Apr issues of 3DO Magazine Japan show screenshots of their work done for the system.
• Multiple magazines confirm Wondertainment did develop two publically-released games, just not under their own name in the end: Web Mystery for Dreamcast and Goraku Ou Tango for WonderSwan.
• Doda - March 2014: Head of Zener Works confirms they were behind one of the system's supposed launch titles.
• Other companies and games were confirmed for M2 before 1997, but Panasonic ghosting every Western developer makes me believe most of those wouldn't have seen the time of day... at least not on the M2.

Nearly 80 games in total, more than 40 from Japan... what other games do you think would've made it onto the M2 had it released?

This early casing for the M2 shows it once had support for all these formats, so I wonder if that functionality was kept for the final kiosk model?

Also I know the 3DO has a cool visualiser for playing audio CDs, and I was wondering if the M2 has a similar function. Maybe it could give us a glimpse into what the console menu would've looked like outside of the very 90s-looking Storage Manager.
