Google! My Maps - What is future of wikimapia?

Google maps has introduced a new feature called My Maps which allows users to customize/create maps by adding placemarks, lines and shape. It's a useful feature, however, I have some doubts.

I am just wondering, what is future of Wikimapia now? In Google My Map, I can see some problems which are redundancy and accuracy of data. Wikimapia was a collaborative environment which means it allowed others to rate/review any changes/addition in content (map).
