No definite decision, but yes:
"Therefore, at the
present time, it would be safer to consider Nectocaris pteryx as Din-
ocaridida incertae sedis (Collins 1996). We, however, refrain from
doing so at this moment, waiting for more information on the evo-
lution and diversity of anomalocaridids and their relatives, to be
established. "
Similar thoughts were voiced back in May in the blogosphere:
