From teardown [0] at 3:50 you can see an ARM7 Cortex M4 @ 240MHz, so BASIC or MicroPython should both be speedy enough for most tasks. But from both the teardown and from another review [1] there are some concerns about the bugs and lack of features in Zero's BASIC and MicroPython. The firmware is updatable, so hopefully Zero irons things out, but still not a good look to have this present in a release.
