By the time we see 5E on the shelf 4E will have run for 5 years. "Can't keep doing it"? Compared to the 3 year lifespan of 3E before 3.5 kicked it to the curb, or moving from OD&D to Basic you would have nothing to complain about. Sure, it makes one long for the days of 1E AD&D's reign of 12 years but that ended with some 35 hardcover rules books. You don't want to change systems? Don't. As was said nobody is going to burn your books. I bought the 4E core books and immediately shelved them. Bought the Pathfinder rulebook last year. Have hardly even looked at it since. That's ALL I've spent on gaming materials since 2008 and I've been playing 3.5 and 1E.
But this thing of, "can't keep doing it," suggests to me that you REALLY didn't know what this hobby involved did you? Sad that you've had such a rude awakening but I've been playing D&D since 1977 (Holmes' Basic) - 35 years. This is nothing new. THIS IS SPARTA! This is what happens when you play D&D long enough - when you play ANY RPG long enough - you are eventually faced with a choice of play the current edition, move to the new edition, move to an older edition - move to another RPG or another hobby entirely.
Don't take it personally. Whether you knew it or not, THIS IS WHAT YOU SIGNED ON FOR. Aren't you having fun yet?
If you're counting 3.5 as a new edition, it only seems fair to also count Essentials as a new edition.
