It is good to hear such news.
Widely accepting bitcoin will lead finally to accept all the altcoins one day.
Now the question is when this day will come?

Altcoins will never be used as a real currency there is fair to many unless it can take over bitcoin.
Too pessimistic
That's true many altcoins are doing very very bad but not all of them, few sites accepts altcoins deposits like direcbet (dogecoin, dash, Litecoin)...
