is it a good sign that the job interviewer wants to ultimately hire me if he asks...?

to call back in one month when at that time they would have a clearer picture of when they planned to begin hiring their new team? aside from that, things appeared to be positive....he was impressed with my resume and educational background. i was recommended by someone who i freelanced for and this person was extremely satisfied with the work i did for him, this job would entail similar work. he even asked me about how i would get to work (which train line!). on the other hand he was not certain about my specific job responsibilities as yet and did not discuss salary either since he was not sure of the whole picture as yet.....interviewer said that he liked what he saw on my resume and wanted to follow up with a personal interview to see if my resume matched the recommendation and the resume. he was preparing to realize this project only after the first of the year or by feb. so, what do you think all in all?
