Is there anything interesting in Hiro or is it dead ? Any future plans for Hiro

Plenty of future plans for Hirocoin. Take a look over the last page to see what has been going on. We very recently launched a unique feature for Hirocoin not seen in another coin :p We have the ability to import private keys from QR codes within the client software itself. We would not develop such a thing if we were not aiming for the moon

We are here to catch the flood of people leaving Scrypt coins looking for somewhere good to move their funds to. There will be an exodus and for those paying attention we have proved ourselves.
Right now I am helping Evan Duffield on Darkcoin. We are putting in a solution to secure the blockchain against attacks. It is only going to be a matter of time before X11 coins get the sort of attacks that are common on Scrypt. Hirocoin is secure and we are making sure that Darkcoin is also going to be secure.
Once I have finished working on Darkcoin I will be back and plan to implement a in client block explorer. Sounds like a sensible thing to have.
Good news is that Bitcoin seems to be on the rise at the minute, this is good news for everyone.
