I'm no expert, but I wouldn't mind another Rift.
"Typically factories will close for 2 weeks over CNY. In addition to this closure, migrant workers tend to start returning home up to 2 weeks before the holiday commences and may take up to two weeks to return after the holiday - factory impact can be spread over 6 weeks."
Being one of 3 major holidays, seems like everything shuts down which causes many problems as other people have said, people leaving jobs and apparently some bribery. After the last big kerfuffle over delays, I wouldn't be surprised it Oculus is playing a bit safe this time with date anouncements. Again as other people have said, now they have people very familiar with Chinese factory schedules.
Also, happy March guys and gals! It's looking to be a crazy month for everyone, some new speaking events are on Palmer's schedule all over the country, Rifts starting to spread across the globe, and hopefully some news from those 40 or so test runners about what they've been tinkering with whenever the embargo lifts. I gotta know what those guys are up to right now.
