Do you think Nintendo (or a third party) will ever release replacement casings for the DS Lite, like the ones that exist for the DS Phat? That would take care of the "crack" problems.
Say no to crack!!!!
I doubt it that Nintendo or official third party companies will release replacement shells for it as I don't think Nintendo would want people opening up DS lites anyway. There were some chinese(?) replacement shells on sale on eBay though for the DS Phat so maybe they'll make one for lites too, but I mean copying the look of the lite casing is different (or maybe harder to produce) compared to the simple plastic DS phat shell.
On a not-so-related note, at first I thought these were replacement shells made by Hori so I was kinda surprised, but turned out they were just snap-on armor.
