Microsoft may have formally increased the number of Gamerscore points allowed for a single game to 1,750, with the corresponding number of Achievements being 80, according to reports.

The latest on this comes from "several unconnected development sources" apparently. It follows a report a few days ago from Xbox360Achievements.

Previously, it was understood that a game could offer a total of 1,250 Gamerscore points - 1,000 from a boxed game and a further 250 from DLC.

According to the reports, 1,000 points is still the limit for boxed game content, but a further 750 can now be offered through DLC. This reportedly corresponds to 50 achievements in boxed game content and a further 30 in DLC.

There have been exceptions to the previously-understood rules in the past - notably Halo 3, which went right up to 1,750 points and Fallout 3 and Fable 2, which have gone to 1350 points. These were seen as the exception rather than the rule, however.
