Only a few months 4 to 6 i would estimate for nevada the paperwork has already been accepted by the nevada gaming comission !!
in nevada zynga will be a systems provider only !!
bwin and mgm and boyd gaming casinos have applied for an internet casino gaming license because they need to partner with a physical company in nevada for the location of the servers and to have people sign up for accounts online in state only...
in new jersey mgm and boyd operate the borgatta casino so similar there as well with licensing in state.. the big plus in jersey is they will open it up to all casino games except sports betting !!
both nevada and newjersey want to go interstate thru each states existing lottery system or by state compacts such as powerball or megabucks !!
once nevada and new jersey get up and running every state will want to be on the bandwagon.. my time estimate october 2013 !! just my estimation from years of reasearch !!
