Since its a Honda you may be right. Even with good engineering sometimes a plan does not really pan out. Sometimes pretty average motors just seem to keep going. Time will tell.Honda Canada had a cutaway AT engine at the consumer shows in Canada. There are many visible signs that the engine is designed with durability in mind for example coated full skirt pistons and conrods that flare at the bottom for increased bearing area. Relatively low compression, relatively low rev limit and modest power output all point towards an under-stressed design. I've been a Honda mechanic for years and it wouldn't surprise me if this engine with regular maintenance would go 150,000 miles (250,000km) before needing any serious work.
