I don't think they're in conflict at all! But Tolle's approach is a little different from the Abraham/Hicks approach. I feel like they each emphasize different aspects of the same thing.
If you're feeling frustrated and discontent with the now, and put the future on an unreachable pedestal, then by the law of attraction you're asking for more discontent with your now. The LoA works for you if you feel excited now with the delightful, tingly anticipation of what's to come.
Steve also writes about how the best goals to set are the ones that improve your life now, in the moment you set them. I feel it's the same for intentions.
