Yeah, there are 9 tones for sure...... don't rely on Wiki at all... Cantonese is a lot more harder than Mandarin in my opinion ;) I took 2 years to conquer in Mandarin; Cantonese? Even My mum is a native speaker of Cantonese, a HongKonger, and she teaches me to speak and to use the phrases...I'm still confused, and i speak with lots of ''lazy sounds''... You needa be very careful with your pronunciation; people might easily get confused for what you've said.
