A North American and European title update and the Australian and New Zealand release for the Wii U's Trine 2 Director's Cut have been "stuck in the submission process," but the developer hopes to resolve the delays by the end of January, according to a post on Frozenbyte's blog by marketing manager Mikael Haveri.

Haveri said in a video that, once approved, a title update will bring "better graphics," voice chat and Wii U Pro Controller support to the North American and European versions.

"Long story short, we have been stuck in the submission process and are now once again waiting for approval, although next week is looking promising," he wrote. "Sorry for all the trouble."
