Here is an update on it. Apparently everything was worked out:
"Everyone, my apologies for not closing this out yesterday, but here's our final update. The good news is - it's all going to work out!
As many of you now realize, Walmart had a system error which caused the status of pre-orders for The Old Republic to change to 'cancelled'. The good news is, those orders were in fact not cancelled, but of course, that didn't help everyone's confusion.
In case you have not seen the email Walmart sent to affected customers, here's the text:
(!empty($user->lang['QUOTE'])) ? $user->lang['QUOTE'] : ucwords(strtolower(str_replace('_', ' ', 'QUOTE'))):
Thank you for your recent Walmart.com order(s).
In checking your My Account order history for the order(s) below, you may have noticed that one or more items show a status of cancelled but you did not receive a cancellation email for this item(s). Please disregard the status as it is an error. (If you received a cancellation email for an item, then that item has in fact been cancelled.)
The incorrect cancelled status on your My Account was caused by a system issue that has since been resolved and your item(s) are currently processing and will ship as expected. You will receive a ship confirmation with a tracking number for these items in the next few days and the status on your My Account page will be updated to shipped.
We apologize for any inconvenience this has caused, and wanted to assure you that your products are in fact being shipped.
If you have any further issues, please contact Walmart Customer Service. Be patient and polite and I'm sure you'll get your issues resolved.
We are always willing to try and help resolve issues with retailers and will investigate where large scale issues seem to be appearing, but please bear in mind that generally speaking, in the first instance, please do talk to your retailer if you have problems. Thank you!
This thread was started to discuss issues with those who pre-ordered via Walmart, and as that main problem has now been resolved, I'm going to close the thread. We have no need to discuss people's retailer preferences."
