The developer also hopes for an Australia and New Zealand release in late January.
The update to Trine 2: Directors Cut on Wii U is stuck in the submission process.
According to the blog of the Finnish game developer, Frozenbyte, the hope is the update for North America and Europe to see a release by the end of January. Also expected by the end of January is a release of the game in Australia and New Zealand.
When asked about a retail release of the game on YouTube, Frozenbyte responded, "It's a possibility... we'd need a partner for it though, so even if we decide to go for it, it will in any case take a lot of time to arrange, so it's hard to say when it could happen... we'll see!"
Trine 2: Directors Cut is available on the North American and European eShop.
