The classical long for chess is basically dead. Its boring, with majority draws (close to solved game - de0incentivizing aggressive play). I am glad there is shift towards shorter time formats.
Shorter time control creates more urgency and allows to play subpar moves to throw off your opponent. Its much more interesting to observe.
Armagedon rules are being used now as tie breakers and there is a lot more discussion about changes/rules tweaks.
So who knows what next year will bring.
