The Magpies have recently welcomed back French duo Yohan Cabaye and Hatem Ben Arfa following an extended break after starring in Euro 2012, as well as signing Romain Amalfitano from Reims and youngster Gael Bigirimana from Coventry City.
But with the Tyneside club being linked with a whole host of names including the likes of Lille full-back Mathieu Debuchy, Loic Remy, Douglas and former striker Andy Carroll, Coloccini is interested to see which transfers they will finalise.
"We'll have to wait and see, but I hope so," the Argentine replied to the Evening Chronicle when asked if there would be more signings. "It is going to be interesting.
"Hatem and Yohan are back now, too. That can only boost our players here. We want to see them back and fit again."
The centre-back made his return to the first team on Saturday, playing 90 minutes during the 1-1 draw with Turkish side Fenerbahce, having already missed the club's 1-0 friendly victory over Monaco and 1-0 defeat to Chemnitzer.
Alan Pardew's side took the lead against the Turks through promising youngster Mehdi Abeid but were denied victory by a last-minute equaliser, though the 30-year old is taking the positives from the performance.
"It was good to be back. The pitch was heavy and it was tough because of the rain," Coloccini continued.
"We were disappointed to concede a goal in the last minute. But we have to pull out the positive things.
"We just have to enjoy these pre-season games and look forward to the start of the season."
