Replying to Family guy without Seth Mcfarlane

So due to the recent strike with the writers at fox, Seth Mcfarlane went and joined the ranks of the picketing writers. Since family guy is such a big part of their line up on sundays, Fox decided that they could either not air family guy or hire new people to write it and do voices. And they chose the second. I cant belive they would shaft Mcfarlane like that. Seth does stewie, brian chris, quaqmire and im sure maybe even a few. So now on this sunday they are airing family guy with all new voices and writers. I'd be understandably pissed if i were Mcfarlane and now family is gonna suck because stewie wont even sound the same. They are gonna lose tons of viewers if it isn't very very close to being as random and sounding the same.
