I got one last night and set it up and played it a little bit last night.
After getting it hooked up, I had two updates to download. Getting on the internet was pretty simple..it automatically detected my network and started the downloads. The second download seemed to be going very very slow, so I decided to just restart the system. Once I restarted it, it started the download automatically again. This time it only took about 5-10 minutes to finish the download.
I created my Mii character which was a pretty neat idea. You can create one for each person, it is pretty much like a profile on the 360.
I then tried out each game on the Wii sports game. They were all pretty fun. I don't think you'll be able to play them for long periods of time, but for a short play time they are pretty good.
The controls are very fun to play with. There is a small learning curve, but it doesn't take long at all to get the hang of it. I think it will be really fun for games that take advantage of the new controllers.
It only comes with a regular video/audio cable which I was disappointed with because the picture isn't that great on my bigger TV. I am hoping to be able to find some component cables.
I also have Zelda and Red Steel. I will probably try them later on today since it was so late tonight.
The only difference in the set up is that you have to set up a sensor bar on top or at the bottom of your TV for the controllers.
So far I have enjoyed what I've seen from the Wii. I think it will be very fun with the new controllers.
PS: My EB said that they will receive some more that will be available for sale on Friday.
