TXi will continue as mentioned before. Malibu never been that big supporting athletes preferring to sell boats there way. I wouldn't write off a company as big as Malibu even with their Tommy's issue . If Malibu did ever pull out it won't help the sport for sure.
Australia and Europe do well with the Response, lack of a promo campaign will not affect these markets. Malibu became strong reading the market and constantly innovating. I feel they will be around for a long while.
Malibu are still making Responses, Dennis is no longer with Malibu but that doesn't stop production of the Response. Its a great reliable boat and will continue to fill the Ski Boat space in the market while the demand is there.
