Koei-Tecmo's confirmed to VG247 that Quantum Theory will indeed release this summer.
It was reported earlier this morning that a US KT rep had said the third-person shooter was due for release in that timeframe. KT Europe has told us that was always the plan since its intital delay in February.
"Quantum Theory is slated for a summer release," a rep told us just now."It always has been since the initial push-back a couple of months ago."
Back in February, the company confirmed it had delayed the title until some time "later in 2010".
