Rigol HDO1000 and HDO4000 12bit oscilloscopes launched in China

Unless the -U series specs have changed, it also has a slower waveform capture rate. 30 k/s normally (vs. 50k/s for the regular DHO1000), and 500 k/s in the not-so-useful UltraAcquire mode (vs. 1,500 k/s).

Yes, that seems an obvious consequence of the memory size reduction. But 1000U has separate user's manual. For some reason, they had decided to publish a new manual rather than to update the existing one (the easiest way). Perhaps there are more functional restrictions.
