GUIText and GUITexture on Retina Display?

Does anybody know what happens with GUIText (with Pixel Offset, Line Spacing, and Tab Size -values) and GUITexture (with Pixel Inset -values), on Retina Display?
Will it show up accordingly smaller on screen?

and:
Is there a way to force 480x320 px on Retina Display (to ensure performance if fill rate isn’t four times faster on A4)?

or shall i just shut up and wait till Unity3 is out and i hold an Iphone4 in my own hands?

no i’m sorry meant just to be patient. Or is there anything wrong with question? Do i miss something here?

Pixel offsets are device-dependent, unfortunately. They normally carry over quite well, but the display doesn’t look exactly the same under the different resolutions.
