Eldar are indeed coming.
Path system has been revamped. Autarchs take paths that are now fixed in point cost (before they became more expensive the more you took) but do not make their aspect troops.
Instead it allows corresponding aspects to be taken as compulsory troops.
Ergo, the Path of the Striking Scorpions would allow you to take up to two striking scorpions as troops.
If you also took the path of Swooping Hawks you could take up to two Swooping Hawks as troops or one and one.
Guardians are a lot cheaper and have more options for special weapons.
New transport for dire avengers / weapon platform (with no transport capacity).
And lots of new goodies.
If tau are the long range shooting army, eldar are a mix with potential units in short, mid and long range
Long range comes almost exclusively from heavy support, however so you need to create a mix it seems.
Aspects are still hyper focused and saw a very small decrease in points except fire dragons.
