12 months as Hoshi No Kirby (Kirby Of The Stars) has appeared on Nintendo's latest release schedule.
The new schedule was released as part of Nintendo's Financial Results Briefing and Hoshi No Kirby appears alongside the Legend Of Zelda (Temp) in the list.
However, the release dates for both games are listed as TBA and neither appears in the Europe or US sections of the schedule. It's also worth pointing out that Hoshi No Kirby also appeared in last year's Financial Results Briefing.
Still, his return is long overdue as there hasn't been a Kirby adventure on a home console since 2001 when Kirby 64: The Crystal Shards was released for N64. A Kirby platformer was in the works for GameCube but was never released.
