With e-publishing still evolving, products are likely to be replicated across multiple platforms, from computers, cellphones, flash drives, and optical disks to e-readers and devices that have yet to be created. Sales models are also likely to be varied and will include individual sales, subscriptions, membership arrangements, and tie-ins.
由於數位出版形態仍在演化中，作品可能重製於電腦、手機、隨身碟、光碟、電子書閱讀器以及各種未來還會衍生的科技載體上，而銷售模式也可能是一次買賣（全本或是分篇計費）、訂閱、會員點數、搭售等無法確定的形式。
