apparently it may be being done akin to the Back to Future or MAtrix or Star Wars films with the next two liknking together. The Sentinel issue needs to be clarified. Well actually it doesnt but I'm gonna mention it anyway. Yes it is said that it is unfortunate that with the Sentinels they may not be the enormous wonderful robots but rather be human size. This is not however absolutely out of continuity of the comic. There were originally sentinels and future sentinels reffered to as Nimrods. These in the X-over became human dormant agent machines that were sentinel agents in Zero Tolerance. As well as that in the Current issues of the New X-Men the Sentinels seem to come in all sizes. Either way the script has not been formalised and has certainly been through enough incarnations already...
