Bcash will keep trying but BTC has probably won the battle for now. The whole problem was down to scaling. Bcash wanted bigger blocks, BTC said it was not scaleable long term.

I saw a great analogy:

Thin of a clogged up highway and approaches.

BCash = Lets make the road wider and bigger
Pros - more transactions
Con - you will need bigger machinery, it will grow to unmanageable blocks
You just can't keep increasing size infinitely.

BTC = Off chain transactions
Pros - Transactions are done on the side, kinda like getting people to ride bikes, motorcycles, underground train
Con - Slow to implement

Scaling smarter is best instead of the short term win of larger blocks.
