Well, we know that RAIBLOCKS is certainly on Bittrex's Radar...they even gave it its own ticker, namely XRB, so it's not far-fetched to think that they will list it as soon as they are sure that there are no more issues with the chain.
That said, this is only speculation on my part....
I have a few thousand MRAIS for sale @
1000 satoshis per MRAI. 
PM for details if interested.
Cheers
