Taking a page out of the history book, I think that Red Bull is kind of in a similar position that Coke was in from the late 1930's through the 1950s. Coke believed their product was the best, their strategy was one product, one size - available as many places as possible. Pepsi and others found the holes in that by offering other sizes and better values ( and for some, better taste) that chipped away at Coke's market share. Finally in the mid 50's Coke saw their share starting to decrease enough that they swallowed their pride and started to offer different sizes. Then the advent of multi-slot vending machines led all soda companies to develop their own lines of alternate flavors, to help keep their bottlers from filling up the other slots on their machines with other companies' flavors. Coke survived, of course, because their was more to their success than just product pricing and size. Their marketing, history, and for many, a good product were huge advantages.
Now Red Bull, they have a bit of history, being "first" - but honestly, the product is not that good. Some people have acquired the taste and will be loyal, but the competitors' superior products, in terms of pricing,size and taste, are certainly impacting and will continue to do so. Red Bull offering different sizes was a first step. Customer loyalty will ensure they won't die - at least, I don't expect it to, just like Coke wasn't going to die either.
