I may have missed it, but haven't seen anything about Embraer having plans for a plane bigger than the E195 which is 118 seat in an all coach config. with 31" pitch. Like Bombardier couldn't stretch the CRJ any more, I doubt Embraer could stretch the E195 so anything in the 100-150 seat class to compete with the Bombardier C-series would have to be a new design.
Basically Embraer and Bombardier have been playing leapfrog. Both had 50 seat RJ's, then Bombardier stretched the CRJ200 to make the -700/-900 so Embraer designed the E-Jet for the 70-120 seat market, then Bombardier designed the C-Series for the 100-150 seat market, and now it's Embraer's turn again if Bombardier can sell the C-Series. I think Republic is the only U.S. carrier to order the C-Series so far.
