PS3 Ragnarok platform has been selling since May/June of this year. Thousands of units sold worldwide. Any problems you see are a low percentage of the number of units in circulation.
XBOX360 Ragnarok is relatively new, I think we have less than 50 out there. We have two outstanding tickets where we ended up asking the customer to send the controllers in. I'm waiting on them, not sure if I am going to find it to be a hardware (install) issue or a software (Bug) issue. I can't recreate the issues on my test XBOX360 Ragnarok.
