Yes, it does. It is in the market now, so it came out before now (very recently).

Why “came” is correct? Please give me more explaination.

Hello, P Chanlee,

I’m afraid you’ll have to be more specific about your concern. Why do you think ‘come’ or ‘comes’ may be correct? The action is in the past.
