What does the new " Retina Display" mean for iPhone Developers?

Apple announced a higher res display for the iPhone 4, yesterday. What does this mean for developers? More detection code and image swapping?

Can and should I just develop for iPhone 4 and let iphone 3 and down scale everything?

EDIT:

Perhaps the other way is better?

A: 

Or initially the opposite? That it just pixeldoubles legacy code? Downscaling will probably look like crap.

@jaanus downscaling a factor 2 always looks better than up sampling a factor 2. In the latter case you have to add non-existent information while in the former you already have all info and have to intelligently combine the excess info

If you happen to have any text in the bitmap, downscaling it could make it less readable. For example, a lowercase "m" could be downscaled into a lowercase "n" by removing critical pixels.

@Toad - I agree with Kevin here. Bitmap text will get ruined, probably. Otherwise, you are right, downscaling usually is better.
