Heh heh... WotC didn't push Gnomes out of the first 4E PHB cause no one played them... they pushed them back 9 months to when they knew they were releasing PHB2 that had the Bard in it... since the Gnome was the archetypical Bard race from 3E.I highly doubt Wizards really cares if there's a class people don't play much. It's not like they can get rid of it, lol.*
*Look up that time they pushed Gnomes out of the PHB.
People often forget that WotC had planned from the beginning to have 16 classes available to players before Year 1 of 4E was done.
