We have just submitted our 187 application our employer put the nomination in a while ago & still hasn't had a response, we submitted our application a month ago anyway on the advice of immigration dept & have just received confirmation of receipt of a valid application quoted time is still 5 to 7 months and if you call the help desk it states they have real problems with the new system for ENS & RMNS & info will be updated as they have news. I would hold your breath for a quick result, we've been on our 457 for 3 years.
