No your play through will not be the same, they made food way more complicated in an over hyped patch called, "Hearth & Home".

In addition you will find caves now above the obsidian line if you are lucky. This gave us 2 new mobs. Swamps have 1.

The next 'major' patch will be for mythlands, and I hope it isn't over hyped like H&H was but given the current track record.. who knows.
