I'd be surprised if Roland abandoned a segment they utterly dominate in Europe, the Middle East and Asia.

I predict they'll wind down their manufacturing presence in Italy, perhaps retaining R&D there, while tooling up for the next generation of E-series in China.

As an aside, and FWIW, an ex-colleague of mine who works for a large European Roland dealer reports they're still listing and selling E-80s, with no supply problems.
