I had also heard that when you go to play a game, the game checks to see if your console is up to date. So if you mod it now, and buy a new game in a years? time it might not work, as it will think your console is too old. I do not know how the mod chip would manage that situation.
Just do your research before choosing which Modchip to get - there are some that have a small flash memory for upgrading their firmwares to cope with new Wii firmwares (like the WiiKey, I believe there is a new version of this out that is compatible with the latest Wii board configurations too).
Bottom line is that it shouldn't really be a problem.
