The future features of cloud-based gaming service OnLive got a little less nebulous during the company's GDC 2011 panel. Speaking to developers, its VP of engineering, Joe Bentley, laid out a list of advancements gamers can expect by the end of the year.

Among the new features being rolled out for game makers to implement are achievements (not detailed, but we're guessing these are derived from the console versions), voice chat, game invites and the ability to directly upload Brag Clips to YouTube.

The latest version of the OnLive SDK will also enable developers to let their games support wireless controllers when played on mobile devices such as iPad, iPhone and Android-powered contraptions. (But not actual androids -- those guys hate it when you press their buttons.)
