The RJ manufacturers have a ways to go to match the size of the current

That is much larger than any RJ currently available.

True. I was think more along the lines of the 737-300 series, which had a max
capacity of 149 and a typical (ie SWA) config in the 130s. The Embraer 195 will
hold about 120 with a similar seat pitch- not so far off.
