To me the DSi is like the seperate X360 models.... the only difference being with the Arcade, if you come across a game you can't play due to no hard drive, there is the option to buy one (albeit a very expensive option)
Games that support DSi only will be rare for a while anyway.
So yes, both versions need to be supported just like GB and GBColour
