There is no information backing this up except for Chinese smartwatch site that's just speculating about it. Last year, the Coros Facebook group was aware that the Apex 2 was coming out. It's not the case this year and they've even pushed new features in the Pace 2 like the basic mapping function.
Pace 2 is definitely the most bang for your buck GPS watch out there. However, Coros has some quality control issues and my watch got recalled after two years. They gave me a new one so at least their customer support is quite helpful.
However, their latest releases like the Vertix 2, Apex 2, and POD 2 fell off the mark. I would probably just get a 265/965 rather than an Apex 2/Apex 2 Pro if my current watch dies. Their GPS tracking is poor even with dual-band to the point that they need to release the POD 2 to supposedly make things better.
