Does it really matter what size pyro is towards pew2? If the deal was any top 5 KD or CR (we feel so special to be mentioned explicitly), and there was allready a notice between pew2 and pyro, then bb has no choice but to retract their notice and sit back. Unless they want to dealbreak.
I asume both KD's (pew2 and bb) agreed to this clause in the deal earlier, so no matter the current actual numbers, a deal is still a deal.
