How to filter Next "X" weeks data dynamically

Instead of table , matrix visual could be better for you use case 
where u can add project names in rows section while in date table you can create new column:

Week = WEEKNUM([Date],1)

use this Week in column section

Now create a Numeric field parameter(in Modelling tab) and name it say week_count

then create a measure:
(im assuming your each release is a different record in table, if not change accordingly)

project_count = 
var curr_week=WEEKNUM(Today(),1)
return
calculate(countrows(table[column]),filter(Date table,[Week]>curr_week && [Week]<curr_week+3))

now use this measure in the values section
