Vivendi, the first large publishing house to embrace XBLA with new, original IP, has cemented their place as a leader in the market with the acquisition of two new dev houses. Secret Lair Studio located in Washington and Studio Ch'in from Shanghai, China will join Vivendi's Sierra Online in developing "mid-session and PC online titles".

One interesting thing about these acquisitions is that Secret Lair in the past has boasted about how "Secret Lair is set to revolutionize the MMOG industry". Could this mean that we will be seeing an XBLA based MMO in the future? I for one would be very interested in that.

In their latest investor presentation, Vivendi let slip that they are embracing XBLA full throttle. Later this year, they will be releasing Megaforce and 3D Ultra MiniGolf, while 2007 releases include Incredible Machine, Red Baron, and the title that will no doubt get the most speculation, Battlestar Galactica. While these were the only named XBLA games, there were several other games listed without title or platform that fit into their "short session titles" Categories.

It's certainly great to see the list of big time publishers making their way to XBLA, here's to hoping EA is next.
