.Mobi mania appears to be in full bloom. Sedo's latest premium .mobi auction ended yesterday with some absolutely astonishing winning bids. The previous high sale of a .mobi domain was Flowers.mobi at $200,000 a year ago. If the names in the Sedo auction are paid 

for that record will be obliterated. Music.mobi closed at $616,000, Games.mobi at $401,500, Sports.mobi at $101,000 and Movies.mobi at $82,000. The same bidder, Alvaro Albarracin, apparently took all four of those domains, along with Videos.mobi and Photos.mobi at $51,000 

each. Sahar Sarid has some interesting background on Albarracin on his Conceptualist.com blog. On his own blog, Albarracin said "I am not planning on developing these names, I am planning on selling these sometime in the near future." So the names were apparently purchased as a pure speculative play. That's obviously a lot of money to gamble on a new extension that may never reach critical mass. Of course, if it does catch on these are great keywords that dovetail nicely with mobile platforms. The question is, at these prices, what are the odds the names can be resold for a profit in the "near future" as Albarracin says he would like to do?
