There's been no official word (yet) if this is the end for the device, but it doesn't augur well for future revisions. If you'll excuse us, we're going to go pour one out for the beloved little, erm tablet-thing.
Beginning February 29th, 2012, the Sony Dash developer website will close and no longer support development of new applications. This closure includes the Dash developer forum and Dash developer support, which will close on March 31st. Sony Dash applications will remain available. Thank you for your contributions and we encourage you to continue your development activity on Sony's other platforms available at SonyDeveloper.com
Again, thank you very much,
