I suspect that they will implement confidential assets into either LN or another 2nd layer solution. This is likely where the big money is as Banks spend a lot of money on back office work in settling trades, and have tried unsuccessfully in trying to streamline these processes with blockchain technology.

Further, LN (along with SW) will have so much technical debt, that consultants will likely be needed in order to properly setup LN nodes, and create LN compatible wallets, and the supply of qualified people who can advise companies on how to implement LN will be in short supply, however many of them will work for Blockstream, allowing them to sell their services at high rates -- they will essentially make Bitcoin and LN so complicated so that few people understand how it works.
