Sharp has announced that the Zaurus SL-C700 will be replaced by two new models, the SL-C750 and SL-C760. The C750 features Intel’s PXA-255, 64MB RAM and 64MB ROM. The C760 bumps the ROM to 128MB and has a 1,700 mAh battery.
The C750 will be available on May 24th, the C760 on June 21st.
Update: I probably should have mentioned that these models, like the SL-C700, are only slated for Japan.

Dynamism will offer them.
