There's a machine called the Meticulous which is launching a kickstarter soon which is attempting to somewhat do this. It's a lot simpler mechanically because it's just an automated lever machine (i.e. no pump).

The downside is no steam wand but tbh if I didn't already have a Decent DE1Pro I'd probably get a Meticulous or a Flair 58 and that new nanofoamer pro for milk.
