XZ1 + A3 printing

Hi. I wonder if anyone can help me out with this query. I purchased the xz1 a while back and to acompany this fantastic camera, last night I ordered a Canon ix6550 as I have always wanted to do some larger prints. This morning while at work I had this dreaded thought that maybe the 10mp camera isn't big enough to deliver crisp prints at a A3 size. Can anybody give me some reassurance that 10mp is enough pixels to print quality at A3. Thank you to all that read this thread. Best regards, Ash
