I don't know why anyone would want the original 3DS after the XL launched, considering how much the XL improves on the myriad flaws of the original. I hope that the price cut of the original leads to a cut for the XL because it is tough for me to justify spending $180 for a system that only has four or five full games out currently that I'm interested in (and a couple downloadables too). I'll end up with a XL next year once SMT4 releases at the latest, as my portable gaming needs are more than fulfilled at the moment with my Vita. What can I say, the Vita has a much more appealing library to me at the moment.
The pricing of games on the 3DS definitely needs shaking up though. New games are either priced at $40 (which few 3DS titles have enough content to justify) or $5-10 on eShop with no in between. When compared to iOS prices versus value, most everything on 3DS seems a bit overpriced. The Vita has content from $2 (PlayStation Mobile) to $40 and everywhere in between, and there is meaty content at all price levels. It's just at the lower price levels it may be a PS1 or PSP game. Nothing wrong with that.
Basically what I'm getting at is that the eShop needs two things: an indie-friendly super cheap section for iOS-size micro games and a large expansion of back catalog software from the GBA and the DS. On portable gaming devices, purchasing games wirelessly through a digital storefront is now the norm, and compared to their competitors, Nintendo is slacking.
