Spanish site Meristation is reporting that the Opera Browser for Wii which last week was reported last week as well to be coming out on the 23rd of December will indeed only be a beta version. The beta version while still having flash and all the other features included in the final version it seems its still not quite good to release and guarantee its going to work 100%. Meristation also says the final version will make March, while still remaining free till June. .
