What is the difference between PH315-52-75DE and PH315-52-72EV is SOLVED

The difference is in Keyboard Backlighting and Wireless connectivity.  The 72EV has 4-Zone RGB Backlit Keyboard whereas the 75DE does not. 72EV has Wireless: Killer DoubleShot Pro Wireless-AC 1550 802. The 75DE has Wireless: Killer DoubleShot Pro Wireless-AX 1650 WiFi 6 802. Otherwise than a few components that vary both have same specifications. Release date about March to June 2019 but cannot tell which model variant came first as there are roughly 4 to 5 of them since based on Geographical location and available production parts. It appears the 72EV was more costly to produce and ACER sought cheaper parts for the 75DE or was not able to obtain the original parts being used in production therefore reduced the price. I believe ACER will be only producing the 17 inch Predator laptop for 2020. Beware of 240Hz, 144Hz and 120Hz IPS Screens as each model won't have the same.

I was checking both versions and according to the Acer dashboard, both versions come with the same 4-zone RGB keyboard:

6B.Q53N4.001 KEYBOARD UPPER CASE BLACK RGB CHICONY LG5P_P90BRL INTERNAL 15 STANDARD 103KS BLACK US INTERNATIONAL PREDATOR FONT + SENSE POWER + DISH RGB 4-ZONE BL NK.I1513.0MH

This is strange, but it is on the acer website.
