According to your Design Matters website, the Thinkpad 8 tablet is serendipitously compatible with the Thinkpad Tablet 2 Keyboard. This is not available as an accessories choice when buying the Thinkpad 8 on the US store, however.

The keyboard is not that great, and certainly not worth the premium Lenovo charges for it. If you desperately need a Bluetooth keyboard, consider Lenovo's Compact USB Keyboard, which has a proper trackpoint and full size keys. That said, the USB version is the same size. You'll need a "stand" of some kind, but those are thankfully cheap and plentiful.
