Excellent. We have Colonel Carter there as well as T'eal'c making appearances. The original SG-1 has got to come back. O'Neill is no longer there, but he stories are endless now that the Ori are gone. Plus, stories on helping rebuild Ori occupied worlds would add to the concept.

Always glad to hear news such as this. Already can't wait for the new season, just adds to the anticipation.

As a famous Colonel once said, " See, now we got the band back togther."

Daniel Jackson in Atlantis. What could be better than that. I'm glad they are keeping one of the original characters from the movie around.

Nice i will be looking forward to this episode

the new season airs on july 11th
this is what sci fi had to say!!! The series promises to keep things exciting by introducing a powerful new race, welcoming new cast members and forging new alliances, all while delving deeper into the mysteries of the Pegasus Galaxy. The new 20-episode season will include the series' benchmark 100th episode.

see a powerful new race now whats better than a race that probalbly kicked the crap out of the ancients before the wraith showed up!

the guest stars are
Fan favorite Paul McGillion, returns for five episodes to reprise his role as the beloved "Dr. Carson Beckett." Amanda Tapping ("Colonel Samantha Carter", and Stargate SG-1 star Michael Shanks ("Dr. Daniel Jackson" will also appear as special guest stars this season.

and then theres this i hate woolsey that back stabbing ...

Robert Picardo, known to fans as the International Oversight Committee rep Richard Woolsey, joins the Atlantis cast and assumes command of the Atlantis expedition. Reluctant to step into Colonel Samantha Carter's shoes, Woolsey must deal with new responsibilities and find his way among the crew. The team, led by Lt. Colonel Sheppard (Joe Flanigan), Dr. Rodney McKay (David Hewlett), Teyla (Rachel Luttrell), Ronon (Jason Momoa) and Dr. Jennifer Keller (Jewel Staite), must adjust to his unique leadership style.

Excellent information on the new season, King_of_Atlantis. It's looking to shake up a few things and be a very exciting season.

Indeed, thanks for update... Glad to see our favorite Dr. back. Woosley is going to be different. Can't wait to see were they going with this...
