What will Boeing do after 797?

What they might do is continue on to 8x8 or maybe 8x7, although it really is unknown. Some also speculate that they will skip 797, and move striaght on to 808. This is because 8 is what Boeing is using to denote new planes (787, 747-8). Or they might just get rid of the XyX naming system entirely. This is a possiblity mainly because it was the Boeing 787 Dreamliner. Not just the 787
