Ok, I could be wrong here, but I have a suspicion that the opera broswer may not be free at all. Now, once again, I am not going to try and convince anyone that this is an absolute truth, but just from some simple observations I am beginning to think it may not be.
For example. if you access the shop channel now and click on the Wii Ware button, you see the picture of the opera browser channel with a google image. Now it says on this window that new wii channels can be PURCHASED via this window. This leads me to believe that it is a possibilty, not a definite reality, that at the very least in the future that there may be a pricing scheme involved.
Once again, it is quite possible that we may get it for free, as a sort of Christmas present if you will. However, at the same time, the Wii Ware channel appears to built to use wii points, so at the very least updates in the future will require points.
