First, the good news. Here's a little bit of in-game art for Cave Story WiiWare showing Kazuma in the original and updated sprite forms.

Second, a snippet from the official blog shows us how far along the game is.

“On the programming front I have more recently spent time tweaking the error handling for the Wii as well as putting the final touches on lotcheck. We are currently in the process of being approved for Nintendo’s Wi-Fi access for the DLC back end stuff. ”

We still have bugs that need to be fixed. Probably about two dozen or so minor little ones that we need to address.
