I'm hearing this may be true. Since Bombardier built the Vegas monorails and the system in Brazil, they have the know how and recent experience (templates, etc.) to do this relatively quickly and cost effectively. It will still be a $100+ million dollar project to build 12 new trains, which is probably close to the price-tag that the cancelled theater and space restaurants had. It's finally become such an embarrassment and cost (in comps and other give-aways to disgruntled hotel guests) that they realized they have to do something. They had planned to keep this fleet of monorails running for another 15 years, and they were hoping the new computer control system would help with the problems but it's just a case of the trains having outlived their designed lifespan.
