Colin Edwards says he no longer intends to leave MotoGP for the AMA Superbike championship at the end of 2008.

Edwards switched from the factory Yamaha team to the satellite Tech 3 outfit for what was rumoured to be his final grand prix season, but the change of environment - combined with the increased competitiveness of the 2008 version of the YZR-M1 and its Michelin tyres - has convinced the Texan that MotoGP is where he wants to be.

"There was talk about maybe going back to the AMA [next year]," confirmed Colin, who has qualified on the front row twice from the three rounds so far held, with a best race finish of fourth.

"But it'd be difficult with the bike working as good as it is, Michelin putting in such a big effort and me feeling so good on the bike to say 'see ya, I'm going back to the states'.

"I definitely want to stick around."

Edwards' future plans may also have been influenced by uncertainty over the future format of the AMA championships following the recent sale of the series' promotional rights.

The Texan's rookie team-mate and fellow double World Superbike champion, James Toseland, has already been confirmed at Tech 3 for 2009.
