Doesn't matter in the slightest what the official name is, I strongly suspect it will always be known as Ashburton Grove. After all, who calls Highbury 'Arsenal Stadium'...its proper name.
One other thing to keep in mind; the sponsors name will not be permanent...they will pay for a set period which while being quite a few years, will expire, at which point they may renew if agreeable to both sides or we may get a new sponsor.
