Here's an extract of their press-release:

Pioneer believes that displays are indispensable to its product lineup for these reasons and will therefore maintain its fundamental strategy for the display business—supply premium models with high picture and sound quality befitting the image of its brands at prices matching their added value, while optimizing the scale of its business.

However, we have judged that maintaining the cost competitiveness of plasma display panels at projected sales volumes will be difficult going forward. Accordingly, we have decided to terminate in-house plasma display panel production and to procure these panels externally, after panel production for our next series of models is complete. This move will allow us to transform our business model for displays from vertically integrated, capital-intensive operations to a leaner business model geared to making value-added product proposals.

Pioneer is currently in discussions on the feasibility of procuring panel modules that may incorporate the Company’s proprietary technologies. Details will be announced as soon as they are finalized.

Pioneer plans to review its production structure in conjunction with the termination of plasma display panel production and to streamline the entire display business to a scale commensurate with sales. We aim to compensate for cutbacks in the plasma display business by driving further expansion in our growth businesses.

This will be done by shifting related personnel and other business resources to the Car Electronics business; the professional sound & visual (Pro SV) business, which involves DJ equipment; and the audio/video product business, including Blu-ray Discrelated products. We will give consideration to retaining employees in the course of this process. Details are currently under review and will be announced as soon as they are finalized.
