I definitely appreciate the subtlety of the improvements made. It doesn't change what made the original great, it just brings it up to the level of detail the designers wish the could have brought to the table originally.
I completely agree!!!
guess I'll wait for some sort of updated version Lite or XL style.
Eh, I wouldn't keep thinking that if I were you. For one, Nintendo has stated they don't plan on any revisions, if any, for a long time. When you think about it, there's no need for revisions. The original DS was made lite because it was too heavy...pretty simple thing. DSi was an upgrade that introduced the camera. DSiXL was just another alt version of DSi, nothing was different component wise.
So with all that being said, it's pretty obvious that the 3DS will not have a revision because there's no reason for it, it's only been done in the past to increase efficiency and introduce key features. There are no more key features to come to the 3DS and its physical state does not need improvement, at least enough to require a new system as did the first DS.
The only thing I see being a potential revision in the future, is one with a better 3D display. Apparently, scientists have just recently invented a 3D display screen that isn't merely linear parallax, but changes shape to fit the viewing angle. In short, you can look at it from several angles and move it around without losing the 3D effect. I read about this a few months ago, and unfortunately I can't find the article or source that I read. Anyway, this technology was just invented and if it can even be perfected is highly in the air, so this is all very speculative.
