Lenovo, Tencent, Hasee or Xiaomi. The two last ones could probably not aquire PlayStation, they are too small still but it would be interesting. Xiaomi is still pretty new and will grow huge, no doubt about it. Bigger than Apple? Who knows. Hasee is growing and makes really good gaming PCs, it would be interesting to see them make some console also.
Lenovo or Tencent would be the most possible, from the Chinese market. They are huge, Tencent is almost as big/wealthy as Google, and they push online gaming on PC a lot. Lenovo is also a very big company that could probably afford it as well, and they have been making PC and laptops forever now.
Also Taiwanese companies like Asus or Acer would be interesting.
Other than that I would root for Nintendo, or Samsung as the OP mentioned, to keep the PlayStation brand Japanese/Asian.
