First they never said the on-walls are NOT ported. They were just speculating. They are going by the pictures I assume and probably not privy to the same information as you. I'm sure they go by the information given to them by the manufacturer. Its a first look of a product not a review. Sometimes there is not complete information, hence the speculation. Very common for "first looks" or press releases on a product.
Secondly, they stated that the power bracket had been revised/addressed after M0 review they did. I agree about having a accurate picture though. That would have been nice. But if they don't have one, what can you do? How do they know if there is a new picture if not given one?
Thirdly, they never stated in the press release that the grilles were magnetic on the on-walls. They did make reference to the M0's using magnetic grilles though.
It seems your interpretation on the press release is whats inaccurate.
