I'm still going back and forth on whether to get the Halo bundle in-store with the $30 gift card or get the online bundle. Either way, I'm going to sell the code to a friend for $40, so it's a choice between the Xbox One for $260 or $340 with a bonus game and year of Live. I might do the in-store deal if only to wait and see if I can buy Live and an extra game a la carte for less than the $80 difference.
Sounds like we're in quite similar boats. My plan, fraught with almost certain infuriating pitfalls, at the stroke of midnight on Thanksgiving:
1) Walmart.com, quickly add the PS4 online-only bundle so I can see if there's anything worth a damn for the plus-two games. If so, buy it.
2) If not, attempt a past-the-last-second pivot and buy the online-only Xbone bundle with Sunset Overdrive.
3) Regardless of which of the first two are successful, proceed to Bestbuy.com and snag a couple of games for either my freshly bought PS4, Xbone, or (heavens forbid) the 360 and PS3 I've just failed to replace moments prior.
I'm concerned that the content of Walmart's PS4 bundle won't be known UNTIL that midnight grabbing spree commences. Not much I can do about that, though, other than keep trying your method of search string prognostication.
