New Coke failed spectacularly which is why you will not find one at any store or in any machine. That was the 20th century. We're now in the 21st and the company is apparently hopeful that they can still publicly humiliate themselves. Hence their latest move.
Do you see what's happening?
On the right is the familiar 20 ounces Diet Coke bottle, the type you might find in a vending machine or buy in a six pack. On the left?
That's the 2 liter bottle. If it looks differently to you, that's because it is. They've redone it to indent on the bottom portion so that it now looks like the 20 ounce drink.
Did you lose liquid with the redesign?
No.
But you did gain cost.
Across the country, Coca Cola's got their soft drinks in the newly designed bottles on sale (popular sales include 4 for $5) and consumers may not have caught on yet. But if you've looked at the regular price or paid non-sales price, you should have noticed that you're paying an average of 36 cents more for a 2 liter Coca Cola soft drink product then you were two months ago before the redesign.
According to America's Best Online, Coke just beats Pepsi (in diet and non-diet forms) so it might be of interest to consumers that Pepsi has not changed their bottling and has not increased the price for their two liter drinks. The same can be said of Dr. Pepper which also shows up in the top ten best selling colas.
In 1985, Coca Cola was sent a message by consumers and dropped New Coke (they try to spin the story as a success for the company here). In 2010, soft drink consumers could once again send a message, that they won't pay more for new bottling, by buying Pepsi or Dr. Pepper.
