Well, I found another article with mor einfo:

הקף העסקה הוא כ-20 מיליון דולר והוא כולל רכישה של כלל המושבים במטוסי בואינג 777 החדשים, המיועדים להגיע ארצה בקיץ, ואת החלפת המושבים במחלקות העסקים והמחלקה הראשונה במטוסי ה-777 הקיימים, ובמטוסי הג'מבו - 747/400 של החברה.

עבור 10 מטוסים נרכשו 410 מושבי מיטה למחלקת העסקים, ו-112 112 מושבי מיטה למחקה הראשונה. בנוסף, נרכשו מושבי מחלקת תיירים חדשים לשני מטוסי 777 החדשים.

interesting thing is that for 10 a/c thats an average of 11 First Class (or Premium Business class) per a/c.
With 6 777 and 4 744 -
I think that makes 8 seats in 777 (maybe two rows of 4)
but then you have 16 seats in the 744.
Next option is 10 seats in each 777 (60) and 13 in 744. But how do you fit 10
first class seats in a 777?
Next option is 12 seats in 777 (72) but only 10 seats in 744.
Or maybe they just ordered a few extra. I dont know.
What I do know is that they ordered about 44 more seats then they would have needed for current configuration, so the First Class is getting much bigger.
While the business class is getting smaller - for current confiuration they would have needed (6 x 40 + 4 x 52) = 448 - and they ordered only 410 - thats 38 less.
So it looks like the number of premium seats satys the same, but totally different layout.

In economy they currently have 236/7 seats in 777, but they only got 464 for two a/c - thats 232 per a/c - I am sure they got extra.
Not sure how many extra they got, but it looks like atlest a row less of economy seats.

If they are keepinhg all the seats with 3 class configuration - To me it looks like hey got one extra row in First/Premium J, one less row of J class but with more pitch and one less row of Y.

But i could be wrong, and it could be that some of the a/c might only have one class or two class - so anything could happen.

I HATE THAT LY S NOT GIVING US INFO!!!!!!!!!!!!!!!!!!
