This afternoon Gameloft announced the sequel to Gangstar: West Coast Hustle [$4.99 / Free] entitled Gangstar: Miami Vindication. Along with this announcement is a fairly extensive gameplay trailer compared to the teasers Gameloft usually releases which shows car chases, riding motorcycles, and even piloting helicopters. According to Gameloft, Miami Vindication is "the most ambitious crime simulation ever developed for handheld," which is a lofty claim considering the extensiveness of Rockstar's Grand Theft Auto: Chinatown Wars [$9.99 / Free].
Gangstar: Miami Vindication should be available fairly soon, as looking at Gameloft's previous game releases they generally don't release this kind of trailer without the game being very close to being done.

Also, Gangstar: West Coast Hustle HD [99¢] for the iPad is on sale for 99¢ and for that price is totally worth picking up if these kind of open world crime games are your cup of tea.
