An update on the current status of SEPA can be found on this article (via EuropeVoice.com) dated 27 August 2009.
Regarding a possible binding end-date for SEPA the article says:
The prospect of binding end-dates has been warmly welcomed by the EPC and by large multi-country banks, but has been rejected by business groups and consumers.
Savings banks, which generally have very little, if any, cross-border business, have also reacted cautiously, warning that the market should not be rushed.
Hartsink points out that a legally binding deadline has been set by the EU for all banks to provide SDD by November 2010.
