I missed this when it came out last month, and didn't realize Lotus was committed to staying with KV. Autosport confirmed it:

"Lotus to expand KV partnership


By Matt Beer September 28th 2010, 13:59 GMT

Lotus Motorsport will expand its IndyCar partnership with KV Racing in 2011..."

So if the Lotus plans are true, they run two cars as had been announced at the beginning of 2010. In KV cars, not a new team of their own.
