Ebberon is an awesome game setting, however there really isn't enough support for 4th ed for it yet. I mean you could force a fit, but there are 4 or 5 new races that would be hard to fit in. Unless they've released some kind of support for changelings, warforged, Kalashtar, shifters, Daelkyr 1/2 Bloods...
Can't wait to have our first meeting and get involved in some more games (even run one) also does anyone know if we got any info about including the GFA peeps...
Changelings and dopplegangers are the same thing now, and they are an MM race. Longtooth and Razorclaw Shifters are also MM races, and they show a theme that can make brewing other breeds easy.
Warforged are an MM race and even got an article with good crunch and fluff in Dragon 364.
Have a human take his +2 in a mental stat and give him a Telepathic Bond daily racial instead of an extra At-Will. You now have a Kalastar. Reflavor powers as needed until the Psionic power source is released.
Daelkyr are a special matter; I would make the symbiots racial encounter powers (refreshed upon Extended Rest if destroyed), give them +2CON for being genetically tough, darkvision, and I think that wraps up the package. EDIT: Include a resistance to psychic damage that scales the same as the Tiefling's fire resistance to emulate their land mine of a brain.
So with a little tinkering, Eberron is already there. WotC knows their campaign setting fanbase enough to not disappoint the wonder-child, post-apocalypse, magepunk fans. There's even a playtest article for the 4e Artificer, which, in 4e, is an Arcane Leader with Controller tendancies. They handled artifices well and integrating them into powers neatly without making them a paperwork nightmare like 3.5 Cleric and Wizard.
