Yeah, oddly WotC seems to think that a (save ends) power is better than one that is "until end of next turn", but frankly in most cases the latter type are actually better. Granted they end at a definite time, but (save ends) have a 50/50 chance of ending sooner than that anyway and very little chance of lasting more than 2 or 3 rounds.
You just have to fear those monsters that have them. At least you can plan on the effect ending at a specific point in time.
