Given that iSight and Facetime HD cameras required drivers and firmware to get running under Linux, I would be positively surprised if the new camera is easier to set up, meaning I don't think it works right now. Even the existing camera support isn't 100%, with features like suspend/resume being flaky, all due to it being reverse engineered.
That said, the options for developer laptops has shifted in favor of general x86 computers, including very light-weight machines and ones with mechanical keyboards. If I want to use Linux on it, my first choice wouldn't be a macbook. So, unless you require macos for work, you have have a more diverse variety of laptops to find one that suites you best.
