I know! They re-relese a game that has recently been remade, yet Nindendo ignores other classics like Bionic Commando, Kid Icarus and Castlevania II. I mean, they put out Ice Breaker for goodness sakes!
I think they'll get there eventually.
One thing that is unclear to me is what the rights situation is for some of these games. Up until now most have been Nintendo published titles but Castlevania isn't of course. For titles like Bionic Commando Capcom would like have a yea or nay (and some level of negotiation beyond that) for it to appear in this series.
Nintendo may end up setting this up like the PS2's Greatest Hits line with a certain minimum number of sales required to be included in the series.
