I think you answered your own question with your post
"Where are all the games? After the console was revealed we saw LOTS of games shown for the system, but we currently have 28 Games released for it, according to VGChartz, with only 20 of them being available outside of Japan."
A lack of games is holding the system back quite substantially, I myself was aiming to get a 3DS as soon as possible (I wanted one at launch), to play all the amazing announced games, but after the price in the UK was originally announced to be £230, I didn't have the cash to buy one, so I waited, and a good thing too, I alredy have a huge back catalog of games, there aren't many compelling 3DS titles right now and the price for a 3DS is now £165! :O
I'm not totally sure why the games shipped numbers are so high, but I'm guessing retailers also expected the 3DS to sell like hot cakes, and software sales to match, but now they have to sit on all that extra stock
