Thanks Dreamer,
I saw this post on PSR Tutorial:
"Hello.
Monday was the presentation of the new Tyros 5 in Palma de Mallorca (Spain) and the screen is not touch, but as the current Tyros 4.
There are 2 versions of 61 and 76 keys and the sound is much improved.
The styles are real samples of audio."

May not be true at all. Sorry if it's not.
