Call of Duty: Modern Warfare 2 Map Pack 1

Call of Duty: Modern Warfare 2 is finally getting it's first map pack, but some fans are pretty displeased that Infinity Ward have decided to up the price from $10 to $15 US. A 5 dollar jump is quite large considering this isn't a whole game or even an expansion but only some added multiplayer maps. Tell me what you think of the price hike.
