I kinda got the feeling at mix with some of the Data initiatives Microsoft does a lot of skunk works. Many teams are working on the same problem from different angles and possibly different domains.
Some initiatives die a not so pretty death, others flourish, while others mutate onto the successful version. Competiveness breeds quality.
Popfly- A way to weld web serves together visually through use of a code generator.
MVP- A way to program without using textual code. Big limatation no backend code. Be curious to see if there is any xaml/xml that you could generate.
WorkFlow Foundation- A runtime for running workflows both visually and programatically.
I think it would be wise to weld all three together into the next version of work flow. Lets hope we have a volving story instead of we are deprecating Workflow Foundtion. Or here is a new way to do work flow.
