Also, most of the Acela-1s are leased, not owned.

Right now it appears there is a Keystone that is only 4 minutes slower than an Acela in the late morning PHL to NYP. For a third of the price I will take 4 minutes longer.
The current Acela trains are limited to 135 mph max speeds in New Jersey, the new Acela 2 trains will be able to reach max speeds of 165 mph in New Jersey. That should increase the time savings over Amfleet trains that will continued to be limited to just 125 mph max speeds in New Jersey. 40 mph speed difference over 10 mph speed difference should amount to some more time savings.
Will it be worth triple fares, only time will tell.

Yes those Acela II trainsets will be able to do 165 in NJ down the road and that will certainly reduce some more travel time off the schedule between NYP and PHL over taking an Amfleet set. Remember that in a couple of years, the Amfleets are going to get replaced. That includes the ones that run on the Keystone Corridor. In the next few months, we will know what will replace the Amfleets.

Just remember for the Acela-2s to do they will have to test to 181.5 MPH That is 165 + `16.5 = 181.5 That 16.5 is 10% of the 165 required by present FRA rules.
I have not heard that the tests so far have reached over what 165?

Where in the FRA regulations did you pull the 10% higher speed test from?

FRA regulation on calculating max speed
https://www.law.cornell.edu/cfr/text/49/213.329
FRA regulation on testing max speed
https://www.law.cornell.edu/cfr/text/49/213.345#e

specific clause under discussion lately:
"(2) When stage-one testing has successfully demonstrated a maximum safe operating speed and cant deficiency, stage-two testing shall commence with the subject equipment over a representative segment of the route as identified in paragraph (e)(1) of this section.
(i) A test run shall be conducted over the route segment at the speed the railroad will request FRA to approve for such service.
(ii) An additional test run shall be conducted at 5 m.p.h. above this speed."

5 mph over rated speed is 10% or higher at rated speeds 50 mph or less. At 165 mph rated speed, 170 mph is just 3% higher. Math=170/165 x 100 = 103.030303
