Your analysis is consistently flawed,
There is absolutely nothing preventing a new suit on the 6 PTAB validated claims as well as other patent claims Worlds holds that have not been asserted.
Your comment that the ATVI case has to be resolved before any additional suits are filed is flat out wrong.
CAFC will be completed in 2017, the ATVI case likely will be completed in 2018.
it will not take a year, at most 6 months from the court scheduling pretrial discovery to trial, just look at the previous schedule set by Judge Casper.
You really don't have an accurate handle on timelines and legal options.
