Where is 2.3?

Where is Sonic Robo Blast 2 2.3? If RVZ2 isn't screenshottable yet, then what has Sonic Team Jr. been doing for the past 7 years? I know that devs left and 2.3 had too much ambition, but I feel like the 5-year rule shouldn't be broken for an update that adds 2 acts and remakes a zone.
