Sentinel - I expect a PR for 3 reasons:
1) We have a terrible record of keeping to dates, so when the last one was announced, who believed it would actually happen this time.
2) CES is mostly for deals and intro's, not actual launches as we have now. Plus every company there released a few PR's, who remembers any dates from any of them if you're the general public.
3) We've released Fluff PR's for years with absolutely no substance, for once we have real substance, and we're not going to PR it????
