If 2k will not release any previews this week?

This means that they will surprise a shocking improvement to 2kfans,EAfans and to the EA company because as ive seen so far about the screenshots,gameplay footage,interviews, they did not hesitate on posting previews because they want to show that they are quite enough to compete on any bball videogame thats stands on theyre way and stolen theyre spotlight to be the #1 best basketball simulation in the franchise

Or they're just keeping things under wraps as they usually do.

Or they don't want to release any new info so that fanboys of either Live or 2K can't bash or dick ride their product.

i thinks so.. but if they usually do thing under wrap they should post previews as well if they want that theyre fans and buyer will be satisfy because EA is already posting tonnes of videos
but my expectation is they will post previews with big improvements these year thats it

EA themselves haven't released too many videos of Elite 11. I don't think 2K's released any videos for 2K11 so far, pretty much all the footage has been shot down as being clips from 2K10.
