It's clear Linkin Park just wants to move on making music without looking back. There's not any clear nod at Chester, or any homage at all (at the concerts, songs, interviews...) They're almost pretending it didn't even happen.
Seems like it's working, tho. Of course us, the hardcore fans, would expect more materials connected to Chester somehow, paying homages and such. But they have the right to move on like they're doing.
