By default the price is still meant to show in catalog mode, as this is generally what most users want. If you’d like to hide it all you need to do is add the following to the custom css box within theme options:
.woocommerce div.product .summary p.price, .woocommerce-page div.product .summary p.price, ul.products li.product .price, .woocommerce table.shop_table tr td.product-price, .woocommerce table.shop_table .product-name .price, .woocommerce div.product form.cart .group_table td.price {
display: none;
}
