What is a good way to follow updates on this situation?
The answer to the question I was trying to ask is https://coinbase.com/network/blocks which enables me to check in on how far behind the future legitimate blockchain is (7 blocks at time of writing).
http://blockchain.info/ is updated live.
As you can see, the 0.7 chain has already overtaken the 0.8 chain, and clients are now resubmitting transactions into the 0.7 chain.
