This will never come to android.
Epic: “So we have the engine up and running on Android, and we’re supplying it to licensees. We don’t have any immediate plans in terms of our own games for it yet. Our concerns are probably the same as John Carmack’s. Lots of good hardware, but it’s all over the map, and the rest of the issues he pretty much addresses. It will get there, I’m sure, but our technology can be licensed and used on Android. It’s just not as big a focus for us as iOS.”
1. Android hardware is all over the map, it would be a nightmare to get this game to work well on all devices. For iOS the hardware and software are almost identical for all devices.
2. iOS users are much more likely to pay for a game, while in the android market users are much more careful with their money, they bought an android for christ sake, they are damn careful with what they buy.
3. Android users aren't very loyal, only 71% said they would go for an android phone next, while in the iOS market, 89% said they would get an iOS device next. 21% Android users said their next choice will be an iOS device. Total current market share in smartphones: 28% Iphone, 13% Android. Throw in the iPod touches and iPads, and the iOS market is about 5-6 times larger then Android.
Keep in mind, developers aren't SWITCHING to Android, they are merely porting to get money from both markets. With a game this big, porting would be extremely difficult. Unreal engine 3 games WILL come to Android, just this game, wont.
