Okay, I went into MMB to try and grab a screenshot. Looks like this isn't anything interesting (aka a new plane), just another CX IT blunder.

On MMB, this is clearly the 3-class KA A330. Rows 22 and backwards are 2-4-2. Rows 16-18 are available for elites to book, basically "business" sold as economy.

For some reason, when booking the tickets the new IT interface screws it up and makes all the rows in economy 2-2-2. Effectively eliminating 2 seats. Brilliant. I have to imagine there are going to be plenty of unhappy people when they check-in. I wish I took a screenshot of it.

I guess there is some glitch that when CX is going to sell some rows of biz as economy, it screws up the rest of the economy seat map during the booking process. Basically the 2-2-2 section (which is accurate for rows 16-18, although this was unavailable during the booking process) is filled down for each economy class row for the entire rest of the plane. Oops. It is accurate in MMB but not during booking.
