There will be new stuff coming & going in the market & it's a matter of preference if you like it or not, have a personal want/need for it, see the benefit in having it, the list goes on.
Biggest issue with "new" bicycle tech [innovation] is when it replaces something that is very similar to it predecessor [should it happen] . If a 11 speed E-shifting system took away entirely or made it severely hard to get the 11 speed cable shifting system, then there will be "war" .
