The Boeing 737 has seen an update about a year or so ago and it was a pretty good update with more liveries, wingflex, APPR, and new landing gear. However, with the Airbus a320 family as well as the brand new a350 having live and working instruments, lighting, and master switch, the Boeing 737 should also get these features as well as other Boeing models such as the 777 variants as well as the 787 dreamliner variants. Since some of the Airbus planes have these features, why not have them on the Boeing planes as well.
Live instruments will be added to all aircraft as they are reworked. The 320 paved the way for others to follow. Stay Tuned!
