Votes speak louder than words. Even though the 787 is nearly the same as the a350, they both have similarities and differences. The DEVS just need time to realize that this great aircraft should be in Infinite Flight. The a350 was a runner up for the poll, So obviously the community wants it.
@Sudhanva_Ganesh No, we only know that the CRJ rework is underway. After its complete, there will be another poll.
