It seems like the de jour solution to the Osborne Effect is to create the consumer expectation of significant price increases. People still buy last gen hardware nowadays well after the new hotness is out, because the new generation often costs 50%-100% more for a year or two. If Osborne had said "The next versions will be even better, and only cost $5000 more!" people would have kept buying the Osborne 1.
There will be a bigger backlash if they mislead customers on the price.
I really doubt there would be a major backlash if a company like Apple said "Due to , we are able to offer the new iPhone for $XXX dollars less than we expected!"
Consumers rarely complain about lower prices than they expect.
Hell, tons of companies offer their products at an MSRP that drops massively within weeks.
