> Maybe it will really beat the keyboard for writing in Chinese or Japanese
It seems very unlikely, at least with Japanese. In my experience, a typical Japanese native speaker (who is accustomed to the computer) can enter text with a keyboard an order of magnitude faster than they can write it. The difference becomes a bit less stark with tiny keyboards on phones or whatever, but even there, most people these days are a bit shaky when it comes to writing complicated kanji anyway... ><
Writing has other benefits of course, e.g. that you can easily enter a character which that you don't know the pronunciation of (which is why it's commonly supported for dictionaries), so it's a useful feature to have even if it's not the primary input method.
