Well, at the very least Nintendo actually has to put some work into this collection, unlike the SMB All-Stars one where there was already a prepared ROM they could use. As far as I know, there is no previous Kirby Collection for them to just slap on a disc.
As for the collection itself, "meh". Like Dr. Metts, it's rare that I can enjoy a Kirby game so I doubt I'll pick this one up, though I did like Super Star Saga on the SNES/VC.
