So here's what I think. I think it would be really nice if you could transfer the DSi Points you have over to your Wii and use tem as Wii Points, and vice versa. I thought this was something that would be possible at the systems launch, but I guess not. But wouldn't that be cool? Do you think Nintendo would ever do it?

Nintendo won't do it, they would prefer you buying the respective points card for each system because it makes them more money. Besides, it would probably be a pain in the a** to come up with a way to keep track of point transfers between systems.

I don't want to transfer my free 1,000 DSi points because I'm waiting for GB/GBA downloads!

I don't think that's necessary. I mean, if you don't plan on nevery buying anything ever again on one of the systems with the points you got left you don't lose anything. And Nintendo never said you can transfer the points, in fact: why should they do that? You can't transfer your money on prepaid phone cards too, you can't transfer money between different Xbox Live accounts, ....
