Not surprising at all...
In other news... Windows 10 will have a start menu.
Thats because they at least accept they got it wrong

My issue isn't whether BioWare misled anyone - they do however accept that they misjudged what PC players wanted from a Dragon Age game. If they don't/didn't accept that, why this>
With the release of Dragon Age: Inquisition, we've been hearing a number of concerns from members of our PC community, including:
- Driver support
-
- Hitching and frame rate issues in cutscenes
-
- Feedback on keyboard and mouse controls
-
- General user interface optimizations for PC
They also acknowledge there are technical problems with a game they released - after telling everyone that they would delay the title for polishing - and that the resulting experience would be worth the wait. 
No my issue is that no one still has any idea what they will in effect fix and when and oh btw in the meantime we'll stick our heads in the sand * as the storm continues to blow right over our heads (* insert appropriate UI expletive description as you see fit)
Did they break promises, did they mislead it depends on your individual perspective but with the statements they made in the OP - that part is unquestionable proven.
