Sounds good but proof is in the actual gameplay shown off and announcements made.
True. Here's hoping for a great e3 showing from Nintendo. Im optimistic.

The thread is months old, but exciting information.

In Topic: Anyone else having this problem with their gamepad LCD screen?
16 December 2012 - 03:17 PM
Once you turn the screen on, it doesn't really show.
What you have there may be Newton Rings. The "gasoline" like mark you see is caused by interference between rays of light reflected by the top and bottom surface of the very thin air gap between the two pieces of glass. In Wii U case its one piece of clear plastic and glass. Although figure 1 shows an ideal situation- it gives you an idea of why Newton Rings form on the Wii U gamepad. Google Newton Rings for more images.
Figure 1. Basically the two bands of light interact with one another to form rings of light and dark areas, or rainbowy colours. This is because the light ray reflected by the flat pane of glass has to travel a further distance (Δy), and is out of phase with the light ray reflected by the curved glass.
Now why would the Wii U's gamepad do this? Well because of the nature of the resistive touch screen. Unlike capacitive touch screens which has two straight glass panels, resistive has one lower glass panel and the upper is a flexible plastic screen (In figure 2 it is Polyester). Like trying to stretch out a really big bed sheet with someone so its perfectly flat, the middle of the bed sheet will alwase be "domed" down due to gravity. My guess is that the Polyester upper screen (Assuming it is polyester, which is a plastic) domes downwards a little (due to gravity? electrostatic force? Not %100 sure.). The upper plasctic surface being curved and the tiny air gap underneith causes this circular interefernce pattern we call Newton Rings.
Figure 2. Wii U vs Ipad (I know the top sais figure 1 lol, just bare with me XD)
I don't know why the game pad has that particular pattern in that location, perhaps its wrinkles in the material or local depressions in that spot or maybe its humidity causing the material to warp (I'm not a materials expert). Most images and figures are highly idealized anyways, which means in nature it doesn't alwase appear as nice concentric circles, like figure 3.
Figure 3, Ta-Da!
Please excuse any bad writing and please feel free to criticise any bad science(science is about disproving a theory until you find one that can't be disproven!). This is just my theory on why there are "gasoline" marks, feel free to interject.
Also hot blowdryer and plastic isnt a really good match... seriously though you can only really see it when the pad isn't displaying anything, no biggy. I've been using mine like like that since launch, it really not noticeable in my opinion. The call is yours to make if you want to take it back, but I personally wouldn't try to fix it by heating or anything, it may warp the plastic top Resistive Screen surface (and void the warrenty).
***Update***
Heres a solution I found on Acer's phone website.
Newton rings on touch screens
Why do I see alternating light and dark rings on my touchscreen?
In some cases, you may see light and dark circles show up on a touchscreen. These circular reflections are called Newton Rings and do not have any effect on the proper functioning of the LCD panel or on the touch functionality.
CAUSE
Due to temperature or pressure differences, the film used for the resistive touch screen may not perfectly adhere to the glass layer of the LCD panel. This can cause reflections showing up as coloured rings.
SOLUTION
These rings go away as the panel warms up during use, and may return again when the system has cooled down. Their occurrence is a known limitation of the used technology and does not indicate a product defect.
awesome, thanks for posting that!
I wouldn't jump to conclusions as the plastic isn't exactly flush around the ends, I believe its to make it easier to remove.
The plastic also never guarantees dust free, its only to prevent scratches during shipping not dust. Its perfectly possible for dust to get on the console at the factory before they even put the plastic on.
The real question is, does the console work properly?
You're right. I brought the new one home today and the film coverings looked the same as last. What's strange is it was packed slightly different. There was green tape on the console holding all the ends together. The gamepads foam cover looked a little different.
So I guess not all will be alike.
This ones gamepad also had that water mark on the screen. So this is normal. Like people said on neogaf, this can be dryed out and will eventually go away.
