The EK50 was essentially a stripped down PA300, so yes a lot of the styles were re-used.
Heck, one of my friends is a huge Korg fan, and still loves the PA1000, and had been looking forward to the PA5x for 5 years... but when it arrived, he was underwhelmed at how many styles were re-used (about 2/3 are re-used). I told him to lower his expectations for that since *everybody* re-uses old styles, and then adds new ones. I mean, if they were so good and you really enjoyed them on your older keyboard, why would they throw them all out? Happens on any brand.
I would've loved to grab the styles out of the korgs, but they've made it insanely obtuse to do so. In particular I would've loved to grab all the Beatles styles out of the Korg Liverpool, and of course the ultra modern ones from the PA1000/Pa4x and now the PA5x (which I did find how to export the styles from PA5x/4x, but again without a hex editor handy, and no frame of reference on the new style header file from Korg, no idea how to extract into a Yamaha style).
Although I suppose we *could* always record a midi file using all the style parts and then feed through the brilliant Jorgen Sorensen's midi to style...

Oh, and the PA80 era arrangers styles? A lot are *still* used to this date, including on the PA5x. Hey, they were really good!
