I think the new haste is excellent. Affecting all or most of your group, it will certainly have much more damage-dealing capacity than a fireball, although over a longer time period. Throw into that movement, AC and a Reflex bonus and this is one very nice spell. I think it still goes toward the top of the list of third level spells.
For those who think it should be a second level spell, it would be freakishly overpowered. I mean, look at how much it increases damage done in just the first round after casting. Assuming just two fighter types, they will each get one more swing that has a high likelihood of hitting. The party is at least fifth level (access to third level spells), so maybe another 15 to 20 points per fighter? That's just the first round. It keeps going for 1/round per level.
