This is all totally normal. They all develop at different rates and times.
DD cruised for a good 6 weeks/2 months before she stood, and then a while longer before she walked. She took her first step at almost 15mo.
I have a friend whos dd is 16mo and she isn't crawling or standing with support, but she sure can chat!
He will do it when he is ready! Be patient and try to enjoy the quiet before the storm as things really change when they are walking!
