They've been saying Toys R Us would go out of business for like 5 years, so it should come as no shock. Same thing is being said about Best Buy, so don't be surprised when that happens too.
I ALWAYS did the Xmas toy shopping at Toys R Us because I could get something for all ages, all interests, in one shot. That was the nice thing, but other than that, I never had a reason to go there really.
When you get stuck in the situation where you don't have the money to compete, you'd better recognize it early. See the trends and where things are going and who is taking over your market share (amazon, walmart, target, etc...) or you will be the one left behind and that's what happened here. Toys have specific seasons and a seasonal business isn't a good business model that will survive by itself - that's why Amazon, Walmart and Target don't have the same issue.
