In a late surprise on day two of E3, Nintendo of America has released the charming Rhythm Heaven Megamix on the 3DS eShop. It combines rhythm levels from previous entries in the series along with all-new stages and 'remixes', and has a price tag of $29.99 in the US.

In addition to the game going on sale there's also a demo available. Sadly this only applies to North America; at the time of writing neither the demo or full game are available in Europe, where it's called Rhythm Paradise Megamix.

Are any of you in North America planning to pick this up?
