Normally when yamato says release in a certain month, normally the ymean the very end of the month, eg July 31st. In this case, it it would be a delay slightly over a month.
Besides, the CF 1A was suppossed to be out in August (as in later thanthe VT-1), but it kinda swapped places with the VT-1.
So, it is not exactly 2 months delay, though it does stretch over 2 calendar months.
