Plarail TOMY Thomas NEW RELEASES

Hankyu sure looks great, and 225 Series Special Rapid Service has really nice station announcement sound, and I have them both and like them very much, but come on! They were released on October 27th 2016, and March 16th, 2017, respectively, and they are still selling everywhere. So why on earth is a re-release so necessary? There are dozens of other commuter train we commuter lovers would want to see (also re-releases, but not so recent ones). Enoden 20 or Osaka Loop Line with the new motor would be just fine, for example, thank you.

EDIT:

Now we have more information and pictures, and so we know Series 225 Special Rapid will lose it's best feature, the nice and rather unique station announcement and stopping sounds (you can hear some of them in my last year's video here). Instead, it will now have "the special connection" (the ability of coupling two trains together): 


The number is the same, S-42, so the old sound trains will go out of production.
Also, the sound model had two speeds, and the new one will have the newest Plarail one-speed-motor.

I didn’t find any differences on the Hankyu 1000, so it remains unclear why they decided to re-release just that latest train from 2016, and not some of the earlier Hankyu train models that haven’t been in regular sales for a long time.

As for Shinkansen Series 500, it will have "the light of great power":



I can't tell the difference here, because the previous 2014 release also had the lights (maybe the light is now stronger?).

Shinkansens are not my cup of tea, but the fans had some complaints - the colour blue was supposedly too dark on the 2014 model:



The colour of the new one does look a bit brighter, but of course it could be just different light conditions:


It will have the same "S"-number as the previous one (S-02), so the 2014 model of the same train goes "out of print".
