Luton's future remains in doubt after the deadline for prospective buyers expired on Monday with no news on whether a new owner had been found.
Blackwell drew encouragement from his team's draw with Liverpool
An announcement is not expected to be made until Tuesday at the earliest.
The cash-strapped League One club were put into administration on 22 November, earning them a 10-point deduction.
Manager Kevin Blackwell had hoped the club would be a more attractive prospect after they earned an FA Cup third-round replay against Liverpool.
Surely anybody looking at that must think Luton's got something going and want to be part of it

The Hatters impressed in their 1-1 draw with the Reds at Kenilworth Road with a lucrative replay to come on Tuesday, 15 January.
Blackwell told BBC Radio Five Live: "It was a terrific team performance and it was thoroughly well deserved.
"What we have done is hopefully given a buyer out there a chink of light and made them think that we are worth a gamble on.
"If we've done that then the lads have done all they can to save the football club."
The replay at Anfield will bring in £250,000 as the club fights for its future.
The League One outfit, currently in administration and struggling to pay the wages of their staff, will be forced to sell off their best players should a buyer not be found.
"But you have to live in hope and that hope was given by a fantastic performance by the players," said Blackwell.
"I don't want to lose a side I am starting to build here. That is the frustration.
"Surely anybody looking at that must think Luton's got something going and want to be part of it.
"All we can do is the football but if we can make it as attractive a proposition as we can, it must help a buyer come in and please God, we've done that."
Blackwell said that the worst part of the situation is that the club went into administration without any warning.
"Nobody was prepared for administration, which means no wages and that has caused a few problems because there are a lot of lads here at Luton who don't earn the money that can see off a rainy day for longer than a week or two."
