Splinter Cell trilogy MP?

I can't find any info on the MP of these games. Is it confirmed or not? I absolutely loved the MP in all three of these games! It was a refreshing change from FPS multiplayer I normally play. I have to say that this is a buy or not issue for me. I've played the single player and loved it, but without that innovative MP I have to admit I will probably skip this trilogy :(

No MP, but tbh, I never played the MP in the first place, it's one of the best SP experiences I've had though.
