new bingo sites 2010

Just saw this webs.com site about new bingo sites 2010. It gives a nice view about why so many new bingo sites have just been launched from a behind the scenes perspective. It mentions who is behind some of these sites, for example, according to what is written there, both tasty bingo and red bus bingo, two of the highest profile new bingo sites in the UK, are both coming from the makers of wink bingo, a name anybody who ever played bingo online will surely recognize. I wonder what would compel them to launch two new sites when they have such a great brand and site running already.
