what do you guys think about this theory for early bearing failure: Engine break in for first ~1000miles generates a bunch of metal in the oil.

Bearing wear begins and once the smooth wear layer is gone its just a matter of time before you get spun...Opinions?

None of the oil analysis show any elevated metals or other signs of abnormal wear.
If you have enough break in metal in the oil to cause damage something went horribly wrong in the manufacturing process. I mean really, REALLY, wrong! Break in metals are on an almost microscopic level.
Cold start bypass applies all year round not just in winter. It refers to engine not ambient temperatures. Most failures to date have been in hot weather. The wear metals are introduced after the filter anyway so they will always exist in the system someplace before being filtered. This is the same in all new engines.
This does bring up the possibility of bad bearings but with what we know I would place that way way down the probability list.
