Speedzone cells are offering these matched now, he posted about it here a little while back, they have similar #s to IB's and have been holding up a lot better.

From that list is it safe to assume that 4500 and 4600 batts is or are going to be legal.

Eventually yes. But the 4500 and 4600mah cells still need some further development in order to get them to the ideal voltage and resistance. For now, the current 4200s are plenty.
