I read the statement and to me, the future progressive seemed to be the most apt way to phrase it. When I tried to find examples to illustrate why, it occurred to me that the future progressive predominates when delivering bad news. For example:
"Unfortunately, we won't be renewing our contract with you"
or
"We regret to inform you that we will be going with another candidate"
Changing those to the simple future makes them sound much harsher to my ears, so I would venture that the progressive is a mechanism for softening the impact.
