Since it looks like we won't be seeing an Alias reboot or reunion, you should be watching "Nikita" on the WB, which is a great show and really comes close to capturing the Alias feel. There's plenty of intrigue and espionage, a good helping of spy vs. spy, and of course, a heroine that kicks booty. Lindsy Fonseca really channels Sydney as her character works as a double agent in an organization not unlike the Alliance. Maggie Q may not wear as many wigs as Sydney Bristow, but when you're having this much fun, who cares?
If you watched the February 25th episode of Fringe (and if you didn't, shame on you) then you likely noticed a bit of Alias lore return. The episode, which flashed back to the 1980's, showed a young Olivia taking stress tests, including the Project Christmas puzzle Jack gave to Sydney, which of course was featured in the final episode. You can see the puzzle, partially assembled, in the pic to the left. I would imagine this isn't a mistake using props, as this is a Fox show and Alias used ABC's prop department. I would guess this is a deliberate reference. It's kind of cool to think Fringe and Alias are set in the same J.J.-Verse. Given the wide appearance of Slusho in J.J. movies and shows, one must also assume the Cloverfield monster and Captain Kirk live in this universe as well.
