Well, at some point, they need to leave the middle ground and make a decision. I think it will be better if this will made as soon as possible. People are getting tired because of these and it will not be healthy if they will drag this for so long. Or maybe, they are just playing with both BU and SegWit while at the end of the day, nothing will happen? 
There will never be a middle ground.
Correct, nothing will ever change on Bitcoin. But Litecoin...
Core hasn't been keeping the system updated, and their refusal of further updates and generally increasing the Block size is alarming and drives support away. The bitcoin unlimited bound failure doesn't lift any responsibility away from the core devs..
Entirely incorrect.
Bitcoin will never be updated and doesn't need to be updated.
Please read my posts in this thread and click the links do some extensive reading and thinking. You will learn about the absolute importance of Litecoin for Bitcoin's future.
Until you re-orient your thinking to the reality, you will be hopelessly confused.
No disrespect intended. I am trying to guide you to the truth, but you have to be willing to click and read a lot.
Core hasn't been keeping the system updated,
There's a very steady stream of updates from Core. They've also provided the protocol change that they think is best. It's sitting there waiting to be used right now.
Waiting to be used on Litecoin. Never will be activated on Bitcoin. Satoshi designed the game theory of Bitcoin so that the vested interests would never be able to agree on modifying the protocol. Otherwise Bitcoin would have no value as power broker money. Please learn that the tail does not wag the dog in finance. Go read please.
