The Lost Developers where are they now?

I really want to know what happened to some of the devs of the past
Where they bought?
Did they change name or merge?
Team members breake up and form new companies?

I don' t know or remember all of the devs but:

MicroCabin
Kokopeli
Altron

I know there are lots more but can anyone give any info of other lost Developers?
Don' t hesitate to list and same ones if you want.

As an example:
Sonic Software Planning (Shining Forces but not Neo)
is now Camelot Software(Golden Sun and Nintendo Stuff)
