Gameloft's already responded. What's interesting is that a lot of their games (like NFL 2011) directly compete with a lot of EA games (like Madden 11).
In short, EA has kicked off a price war, and there's a time limit on this one. Apple is freezing the charts on December 23, which means that any games in the top 200 at that time will remain there over the all-important Christmas holiday, the point at which we've seen the biggest jumps in App Store sales (due to all the new hardware out there under the tree).
