NIH posted NOT-OD-13-064 today via the NIH Guide, which provides information on funding levels for federal FY 2013. 
From that notice:
FY 2013 Funding Levels: Non-competing continuation awards that have already been made in FY 2013 were generally funded at levels below that indicated on the most recent Notice of Award (generally up to 90% of the previously committed level) as described in NOT-OD-13-002, NOT-OD-13-018 and in NOT-OD-13-043. Such reductions may be partially restored, but are unlikely to be restored to the previous commitment level. Therefore, non-competing continuation grants (research and non-research) including those that remain to be issued in FY 2013 likely will be made at levels below those indicated on the Notice of Award. Commitments for continuation awards in FY 2014 and beyond will remain unchanged. The NIH will make an effort to keep the average size of competing awards constant at FY 2012 levels, but is likely to make fewer competing awards in FY 2013. The NIH awarding Institutes/Centers (IC) will develop and post their fiscal policies consistent with overall NIH goals and available FY 2013 funds.
Additional information is included continuing the existing policy to not allow inflationary increases for most competing awards and maintaining Ruth L. Kirschstein NRSA stipend levels at their FY2012 levels. NIH intends to continue to support new investigators at success rates comparable to those of established investigators for new R01s.
