Pardon, but the one who has to calm down especialyl since I'm the one who's asking for evidence.
I know these rumours that the B has a bigger radome, but - honstly - so far we have not enough clear images in direct comparison to an A and these "eyeballing" is IMO as reliable as measuring RCS for stealth aircraft by the same method.
Therefore and not meant as an offence: The so far single image of No. 03 is IMO too blurred and too small to decide and if you have better images or proof that it IS - not looks - wider I would be happy. Otherwise don't be angry that I'm quite reserved to wait for harder facts.
