Since then, Boeing has been looking at distilling the two-aircraft NMA programme into one new 757-style plane, while studying a more modest 767 upgrade, sources said.

I think it is pretty funny, that one of the most discussed potential aircraft revivals on A.net is actually going into a direction, probably nobody would have expected (but many hoped). But to calm things down before everything goes crazy: the "757-Plus" is just a nickname, therefore nowhere it is said, that they are bringing back the 757! For me it sounds like a plane on an existing platform in the size of an upgraded 757. So basically a NMA, which is not a clean sheet design.
