Yes. They went from a dedicated power port plus data ports to a single port which handles power and data. They won't reverse this to add an additional port, as the current case has no room to do so. And MagSafe can't handle power and data without it becoming a huge, unwieldy, 8-10 pinned magnetic block which would also not fit in the current case.
This is the way forward for non-power-user laptops. Single-port connection, ultra portable, long battery, predominantly wireless.
Get used to it, or get the pro-lineup.
