That's not required. Everyone who individually switches to new
transactions gets to do 1.75x more transactions for the same price
(and at the same time gets safer contracts, better script
upgradability, and more security models at their disposal), completely
independent of whether anyone else in the ecosystem does the same.

So hypothetically if wallets/payments processors/full nodes adoption

will take 6 month to get to 50% after the segwit soft-fork activation, this

means that actual network capacity will be increased by:

1.75 x 0.5 + 1 x 0.5 = 1.375

after six month.

An hard-fork on the others side would bring 1.75 since the activation, am I right?
