If you've recently checked your Japanese PSN account, you may have noticed that PixelJunk Monsters Encore is already available for download. The expansion pack that brings you to the whole new Toki Island, adding in 15 new missions, is priced at ¥600 (US$5.77).

That's all well and good for Japan, but what about North America? Will we be seeing a similar price point? And where exactly is our North American expansion? It was given an ambiguous April 2008 release schedule, but has yet to come out all month ... until now -- at least for Japan anyway.

We're probably jumping the gun on this one. The North American PlayStation Store has yet been updated today, so there's still a good chance this much wanted add-on will sneak up on there. Although, a stealth release is not of the norm; if the game was ready, we would have heard about it by now. We guess we'll find out soon enough, won't we?

[Update: We contacted SCEA. Encore is currently scheduled for an early May release. And by early, we mean really early. Stay tuned.]
