We have four DSLites and realise it is time to upgrade them (Christmas presents).. I had planned on upgrading to DSi, they seemed the best bang for the buck (plays all the games we have now, a few added extras, same size (not XL), not as good battery life).. But now I see several games are 3DS only.. Is it inevitable that eventually all new games coming out will be 3DS only? My kids aren't too keen on the 3DS (at least what we've seen in the store), but knowing how technology marches on, it seems like we should jump to it even if we just keep playing the NDS and gameboy games we play now.. Knowing we can play 3DS only games is a plus.. Worth going to 3DS, of stay with DSi? They are about the same price.. We use Supercard dsTwo..
