For those of you who like to track dates, Novell and SCO have stipulated [PDF] that Novell may have until July 29 to answer SCO's complaint, now that Novell's Motion to Dismiss was denied.
They haven't said why they need extra time, but my best guess is they are deciding their strategy going forward. There are options to consider, particularly counterclaims and other motions that could be filed, and since they have a new, outside attorney on board, they likely need time to get him fully familiar with the case, so they can benefit from his input. Any time a new attorney comes on board, he may have ideas you hadn't thought of.
It's important to figure out your basic strategy from day one, because as you saw with SCO's attempt to amend its complaint a third time, you can't always get what you want later. Also, if you watched the dispute about IBM's 9th Counterclaim, you saw that there can be repercussions to everything you file with a court in your complaint or your counterclaims. So I am thinking that could be the explanation. It's also possible that there are scheduling conflicts, attorneys on vacation or whatever. So this is just explaining the kinds of things that could be happening.
