May is not that far off... and it's not that Pokemon games are the only ones affected. ALL Wii and DS games that connect over the internet are effected by this. And in most cases the servers are not being operated by Nintento, but by their third party developers.
Up until October I was playing Rock Band 3 EVERY NIGHT(which was due to moving... my instruments are still in storage but I planed to get them back out as soon as the snow melts and I can get to them easier). I have bought around 400 DLC songs for the game. Harmonix always promised that due to the limitations on storage of the Wii that you could delete songs to make room for others and always go re-download your music without having to re-purchase. I have done exactly that on a few occassions. I was connecting most nights to the internet to find people to play with online. That was a huge part of my life that will go away.
I am sure that many people here also have other favorite games other than Pokemon that will be effected by this. It is no small move. And May seems like it is far off, but for those of us that use that service DAILY.... three months is not very far off at all.
I had every intent of RNGing a living dex collection of Dream World Pokemon... cloning them through Pokecheck so I could keep them in Gen V and transfer them to Gen VI. I'm on a massive clean sweep now, RNGing for IV's only and not caring about nature (I BARELY cared about Nature before anyway).
Oh, and we rely on the Wii internet for our Netflix... We do not get cable because of Netflix. So, yeah. Major pain in the but news.
