Boeing was looking to do a clean sheet design, the airlines wanted to keep the same type rating. The presentation micharacterizes that bit of history, but that's what was going on. This follows what made the A320neo popular, Airbus took a older venerable design and re-engined it for higher efficiency.
The 777 got a similar upgrade that did include a new wing design.
Ultimately Boeing is looking to introduce an all-composites design that fills the 737 and 757 roles, but airlines desires for crew commonality might push that back.

Though note the A320 is a newer design than the 737; the A320neo as a result didn't have the big problem of the 737 MAX: because its landing gear was always longer, because it was always designed for high-bypass turbofans, it could easily fit the larger engines under its wings without having to relocate the engine mounting. The 737 MAX is a world away from the original 737 (hell, the shortest 737 MAX is 6.6m/23% longer than the original 737 design!), whereas the A320neo is much, much closer to the original design. The 737 MAX has ~80% parts commonality with the previous-generation 737 NG, yet alone the original 737; the A320neo has 95% with its predecessor, which _is_ the original design.
