Your best bet is to attend your interview with your wife back in Nepal. Since you're not the principal applicant, you cannot do an early filing based on the newly released memo. Your wife must receive her GC first before you can initiate your AOS processing since you're a derivative. The only way you could have done that is if you're filing AOS together with your wife.
Oh wow - I didn't know that - in that case an August or September current date would be way too late.
