In any event, there are transitional provisions, so that it will be 3 years from the date of bankruptcy. so if you went bankrupt on 1 Jan 2012, you will be out three years later, on 1 Jan 2015.
Signed into law but not commenced. Expected next month. The 3 year provision will apply with retrospective effect so it makes no difference and shouldn't stop anyone from petitioning now if that's the right option for them.
I've believe that the final part of the act will be implemented around November this year. Once enacted, it will also mean that you no longer need €1900 realisable assets, you will just require the €1500 or so in fees.
