Yamaha YPT keyboards vs. Yamaha PSR keyboards - What is the Difference?

Want to know the differences between Yamaha YPT keyboards and Yamaha PSR keyboards!

My son will soon be joining as a student in the Yamaha music school. I was wondering what would be a good keyboard for him. I have been reading good reviews about the Yamaha PSR keyboards but then further exploration revealed that there was another series by the name Yamaha YPT.

Can anybody please let me know what are the differences between the Yamaha PSR and the Yamaha YPT keyboards? The written material on Yamaha's official site for the PSR and the YPT series keyboards does not suggest any differences between these two series.

So I was wondering why Yamaha has retained both these series of entry-level keyboards.

Any suggestions would be appreciated.
