No, that's not at all a fair representation. He literally said that they were "great exclusives". There was not even the slightest suggestion that any of the games sucked, just that some of them didn't sell well.
If anything the author was being too kind to MS in that paragraph, by buying into the idea that these were actually exclusives. Especially the deceptive messaging around RotTR's timed exclusivity was a huge mess. It should be really be counted as a black mark and not a redeeming feature of that press conference.
The bit I find funny is this:
Is that supposed to be an example of a great exclusive lineup? Most of it is PS3 thrash. There has never been a better time to launch a powerful console with bad exclusives. The competition doesn't really have anything compelling either.
