How many states are left to vote in the primaries?

At the moment there are about 16 States left to vote. The biggest state still to vote in the primaries is Texas with 228 delegates. Other important states yet to vote are Pennsylvania with 188, Ohio with 161 and North Carolina with 134 delegates. Texas and Ohio will vote on Mar 4, Pennsylvania on April 22 and North Carolina on May 6. In total these remaining big states make-up 771 delegates. The total of delegates of the other 12 smaller states is 480. So we just might have to wait until June 7th when Puerto Rico the last state casts its vote before it is clear which Democractic candidate (Hillary vs. Obama) wins the primaries or it may be left to the super delegates (whoever they are and however that works???).
