Alice V4 was a commercial product released by Aery Soul at Renderosity in December 2007.
Due to some fairly savage criticism, she was quickly pulled from the market.
With slight revisions, she was rereleased for very short periods in April 2008 (version 2), December 2008 (3), June 2009 (3.5), December 2009 (4) and December 2010 (version 4 again). The December releases coincided with the annual Aery Soul sale at Renderosity and were available for about a week each time. I’m not sure if the mid-year releases were actually for sale or were just updates for existing owners.
Alice version 5, by Alfa Seed, is a revised body morph intended to be used with the Alice version 4 head, but they also provide a morph to work with the straight V4 head.
Kielo V3 was fairly similar to Alice, so there’s a chance they will eventually release a Genesis version.
