Sonic the Hedgehog 4 Episode: II

[NICKtendo DS]

There's a possibility of it getting put on a disk later on in a Sonic 4 Complete pack, but there's no guarantee for that either.

If they do this Sonic 3 & Knuckles lock-on* style, SEGA can have my money.

*If I can play as Metal on every stage, it'd be perfect.
