After reading up on Rate Spread, it looks like they are saying that the FFIEC's site will continue to publish the tables.
(Let me know if you interpret that differently, please).

Comment 2 - Bureau Tables
The Bureau publishes on the FFIEC's Web site (
http://www.ffiec.gov/hmda), in tables entitled “Average Prime Offer Rates-Fixed†and “Average Prime Offer Rates-Adjustable,†current and historic average prime offer rates for a wide variety of closed-end transaction types. The Bureau calculates an annual percentage rate, consistent with Regulation Z (see 12 CFR 1026.22 and Part 1026, Appendix J), for each transaction type for which pricing terms are available from the survey described in comment 4(a)(12)-1. The Bureau uses loan pricing terms available in the survey and other information to estimate annual percentage rates for other types of transactions for which direct survey data are not available. The Bureau publishes on the FFIEC's Web site the methodology it uses to arrive at these estimates. A financial institution may either use the average prime offer rates published by the Bureau or may determine average prime offer rates itself by employing the methodology published on the FFIEC Web site. A financial institution that determines average prime offer rates itself, however, is responsible for correctly determining the rates in accordance with the published methodology.
