Firm date (31-10-10) now for Irish DTT PSB Mux launch?

According to Eamonn Ryan speaking in the Dail on 2nd March he wants the PSB Mux up and running to 90% of the population by 31st October 2010. Is this finally the 'official' launch of DTT in Ireland? Do people think it will happen? What extra relays I wonder will have to be up and and running to supply 90% coverage. Plus he wants a 'national' service by 31st December 2011. What % coverage qualifies as national. Same as current analogue reception?
