What is stopping Broadcom from keeping its business in China exactly as it is now, and chopping off the VMware parts in China? Wouldn't that take China out of the picture for the acquisition merger because now VMware in China is no longer acquired?
If that is the case, then maybe that is the plan B and the delay is due to writing up new papers that exclude the parts of VMware that are in China. With the long term view to maybe pick it up later.
