How many other states will follow?

Washington State Residents,​

With the progress of WA HB1240 we are approaching a deadline to complete firearms transfers due to WA State 10 day waiting period on certain firearms. The "Assault Weapons" Ban will become law immediately upon the signature of the governor. The information we are receiving presents an urgent timeline for WA residents to complete their required forms for transfer or purchase and then wait the required waiting period. This deadline is for many AR's, parts and other semi-auto rifles March 18th. Unfortunately due to the nature of the legislation, firearms that are awaiting background check or waiting period must be transferred to the customer prior to the law enactment date. If the law becomes finalized while firearms are in a pending status or waiting the wait period to expire, dealers are unable to transfer the firearm to any WA resident.

I hope not very many will.
Looks like a 2A court battle to me.

Court battles take time and money.
