i know he can play loads but does anyone know how many?

Guitar, bass guitar, drums, keyboards, piano.

He started to learn saxophone to but gave it up which he said he regrets. Dunno why he didn't just learn it again since it's never too late!

Interviewer guy (his name escapes me at the moment): How many instruments do you play?
Prince: Mmmmm... A thousand.
Interviewer: Literally, do you play all the instruments?
Prince: A lot.

All of them. Anywaaaaayyyyy. I know Prince plays lots of different instruments, but I think only he knows the actual count and which ones.

I bet he is a dab hand at the triangle and the penny whistle.
Thats 2.

if he can play the spoons, he hasn't let on yet, i'm waiting patiently for an epic spoon solo.
