Studio president Satoru Iwata confirmed that classic entries in the series will be given a disc release to mark the character's milestone year, with further details to be confirmed.
The Kirby series had sold more than 30 million units worldwide as of December last year. The title character made his debut in 1992's Game Boy release Kirby's Dream Land.
