Cameron will certainly have options. Thursday's fight was billed as an eliminator for a bout with NZPBA champion Sonny Bill Williams, while a rematch against David Tua would also be a lucrative possibility. Those fights, however, would do little to increase Cameron's standing on the world stage.
"Shane needs to decide if he wants a money fight against the likes of David Tua or wants to have a crack at the world title," Higgins said.
Cameron also needed to decide if he was willing to "degrade himself" by getting in the ring with Williams, Higgins said.
Cameron's manager Ken Reinsfield said the idea the Barrett fight was a precursor to a date with Williams was a PR stunt cooked up by Duco.
"Sonny Bill would watch that fight and have a heart attack," Reinsfield said. "So would the New Zealand Rugby Union. You've got to be kidding me. There's no chance. But as [Cameron's] manager I say, 'Hell yes, we'll fight Sonny Bill.'
"Shane doesn't particularly want to fight him but I'd say, 'Shane, half of New Zealand will pay to watch this, half of New Zealand will pay to watch you knock him out."'
Whether Reinsfield is prepared to continue the uneasy alliance with Duco remains to be seen. Reinsfield's preference has been to promote Cameron's fights himself - a route that can be more lucrative for both manager and fighter. However, Duco has an impressive track record of running boxing promotions and has the funds to bankroll a title elimination fight.
While Thursday's display did not erase the pain of losing to Tua in 2009, it did at least demonstrate how fickle the sport could be, Cameron said.
"Look what David [Tua] did to me in that first round with that one punch. He didn't put me to sleep but I couldn't recover. What one punch did to Barrett - he was asleep, he doesn't know where he is. That just shows you how brutal the sport can be. It's not a nice place to be."
Cameron did not rule out targeting either Klitschko.
"It's a hard fight against the Klitschkos [Wladimir and Vitali], but again it's an opportunity," he said. "A lot of people wrote me off, they didn't think I was going to win but I won in great fashion."
