slate #3

Appleが発売予定の新しいiPadは12.9インチと現行のものよりやや大きなものになるようです。
be slated toはすでにブログで採り上げられていますが，「«日時に/…するように» 予定されている」という意味の表現（『プログレッシブ英和中辞典』小学館）。加えて，この単語は「粘板岩」「石板」という意味があり，ここではiPadと掛けていると考えられます。（Koyamamoto）

Apple Slated to Launch Larger iPad in Early 2015: Reports
Insider sources indicate 12.9-in. version is in the works
In the midst of sluggish sales, Apple has been developing larger touch-screen devices in order to see off competition from rivals including Google and South Korean giant Samsung, according to reports.
The new 12.9-in. iPad will be launched in the spring, inside sources told Bloomberg, following the company’s release of a larger 4-in. iPhone next month.
Apple’s 10-in. and 7.9-in. tablets have been unable to maintain a stable consumer base because of the release of larger smartphones by largely Asia-based competitors.
The new iPad’s 12.9-in. screen would be comparable in size to the largest MacBook Air on the market.
